Morris Guitar Serial Numbers Today
Format: 6-digit number (no letters, often ink-stamped on neck block).
Note: Some use first two digits as year:
78xxxx= 1978.
Key feature: Models with no serial number at all are extremely rare – likely prototypes or seconds.
Before you can decode the number, you must find it. Depending on the year of manufacture, the serial number will be located in one of two primary places:
This paper reviews the current knowledge about Morris-branded acoustic and electric guitar serial numbers, their use for dating instruments, and the challenges faced by researchers and collectors. It synthesizes primary sources (company catalogs, ads, and import records), secondary sources (collector databases and forum research), and physical-serial-pattern analysis to present best-practice methods for estimating manufacture date and origin for Morris guitars.
| If serial starts with | Likely decade | Confidence | |----------------------|---------------|-------------| | 0,1,2,3,4 (5 digits) | 1970–1974 | Medium | | 5,6,7,8,9 (5 digits) | 1975–1979 | Medium | | Letter (A–E) + digits | 1984–1989 | High | | Letter (M, S, T) + digits | 1990s | Medium | | CS + two-digit year | 1990s–2000s | High |
Bottom line: Serial number alone won't give an exact date, but combine it with logo, label, and hardware – you’ll get within 1–3 years. For pre-1984 models, “first digit = year in 1970s” is your best bet.
If you’ve recently acquired a vintage Morris guitar, you likely know you’re holding a piece of Japanese luthiery history. Founded in 1967 by Toshio Moridaira, Morris (Moridaira) Guitars became a cornerstone of the "lawsuit era," producing high-quality Martin and Gibson replicas before developing their own unique lines like the Tornado and S-series.
However, dating these instruments can be notoriously tricky because Morris used several different serialization systems across their factories in Matsumoto and overseas. Here is how to decode Morris guitar serial numbers and identify your guitar's age. 1. The Standard 6-Digit Code (1970s–1980s)
The most common serial format for 1970s and early 80s "W-series" (Martin style) and "F-series" (folk style) guitars is a six-digit number usually found on the internal neck block or the back of the headstock. Format: YYXXXX
How to read it: The first two digits typically represent the year of manufacture.
Example: A serial number starting with 75 (e.g., 750421) indicates the guitar was made in 1975.
Note: Some models from the late 70s used a YXXXXX format where only the first digit indicated the year (e.g., 8XXXXX for 1978). 2. The Letter-Prefix System (Special & Export Models)
For certain export lines and specific mid-80s models like the Morris Hurricane or higher-end TF series, you may find a letter preceding the numbers.
A, B, or C Prefixes: Often denote the production month or the specific factory line.
Dating: Even with a letter, the next two digits usually follow the year format. For example, 83 after a letter often confirms a 1983 build date. 3. Labels and Logos: The Non-Serial Clues
If your serial number is faded or missing, the physical appointments of the guitar are your best dating tools. Morris changed their label designs and logos frequently, which can narrow down the era:
Blue/Green Labels (Late 1960s – Early 1970s): These are the earliest mass-produced models, often featuring "Moridaira" or "Morris" in a simple script.
Square Black/Gold Labels (Mid-1970s): Found on many of the high-quality Martin clones (W-25, W-40, W-50).
The "TF" Era (1980s): Around 1983, Morris rebranded many "W" models to the TF series . If your guitar is a TF-80, it was almost certainly made after 1982.
Vertical "Morris" Headstock Logo: This Martin-style vertical logo was most prominent during the mid-to-late 1970s "lawsuit" peak. 4. Modern S-Series and Hand-Made Models (2001–Present)
Modern Morris guitars, particularly the fingerstyle-focused S-Series, use a more formalized numbering system. Format: YYMMXXX
How to read it: The first two digits are the year, the next two are the month, followed by a production sequence number.
Check: Look for "Luthier Made" or "Hand Made" stamps, which indicate the guitar came from the premium workshop rather than the standard production line. Summary Table: Morris Dating Quick-Reference Likely Serial Format Label/Logo Style 1967–1972 No serial or 4-digit Blue or Round "Moridaira" labels 1973–1979 6-digits (starts with 7) Black/White labels; Martin-style logos 1980–1989 6-digits or Letter prefix "TF" or "Hurricane" branding appears 2001–Now 7+ digits (YYMM...) S-Series for fingerstyle; Hand-Made Premium labels
Do you have a specific serial number or a photo of the label color? Knowing the model number (like W-40 or TF-25) can also help pin down the exact catalog year.

Morris guitars, produced by the Moridaira factory in Nagano, Japan, are legendary for their high-quality "lawsuit-era" replicas of Martin and Gibson models. Understanding their serial numbers can be a bit of a treasure hunt because the system changed as production scaled. Deciphering Morris Serial Numbers
While there is no single "universal" database, these patterns are common for vintage models:
Sequential Stamping (Late 60s – Early 70s): Early models often used a 6-digit sequential number (e.g., 271105) that doesn't directly encode a date. These were simply tracked in order of production.
The YYZZZ Format (Post-1974): In 1974, a dedicated code was introduced where the first two digits represent the year and the remaining digits are the production sequence. morris guitar serial numbers
Note: By the early 1980s, high demand caused the serial years to drift ahead of the actual calendar year (sometimes by as much as 4 years).
Model Number "Price" Hack: A common "reviewers' secret" is that the model number (like W-30 or W-40) usually indicated the original price in Japanese Yen (30,000 or 40,000 yen). Higher numbers typically mean better woods and more intricate bindings, like abalone. Where to Find Them Early Rose Morris 1996 - Rickresource Rickenbacker Forum
Morris guitar serial numbers are primarily used to identify the production year and factory of origin, though formats vary significantly based on the era of manufacture. Most Morris guitars were produced in Japan by the Moridaira factory, with some production moving to Korea in the mid-1980s before returning to Japan for modern high-end models. Common Serial Number Locations
Neck Block: Stamped directly onto the wood block inside the soundhole where the neck meets the body.
Paper Label: Printed on a label visible through the soundhole. Headstock: Stamped or printed on the back of the headstock. How to Decode Morris Serial Numbers
Because Morris has used multiple numbering schemes over decades, decoding often requires looking at the first few digits or combining the serial with the model name. 1. 6-Digit Formats (Vintage Japanese Models)
Many 1970s and 1980s Japanese-made Morris guitars use a 6-digit system.
Dating a Morris guitar by its serial number is notoriously tricky because the Japanese manufacturer, Moridaira, used several inconsistent systems across different eras and factories. Unlike brands like Fender or Gibson, there is no single "master list" that covers every model. 1. Where to Find the Serial Number
The Neck Block: Most Morris acoustic guitars have a serial number stamped on the wooden block where the neck meets the body, visible by looking through the soundhole.
The Paper Label: Some models feature the serial number printed on the internal paper label, which also lists the model name (e.g., W-40).
Back of the Headstock: On certain electric or later acoustic models, you might find a stamped number or a "Made in Japan" sticker with a serial number on the back of the headstock. 2. Common Serialization Patterns
While inconsistent, you can often decode the age using these common formats:
The 6-Digit Format: Common in the 1970s and 80s (e.g., 852554). The first one or two digits often represent the year. For instance, a number starting with "7" or "75" typically indicates a 1975 build.
Internal Date Stamps: Some models have a separate, simpler 6-digit stamp on the neck block (e.g., 062501). This is often a direct date: June 25, 2001. Decade-Based Labels:
Early 1970s: Labels often featured "Yoshino Musical Instruments" or older circular designs. Late 1970s/1980s: Standard "Morris" rectangle labels.
Modern (2001–Present): Serial numbers are more standardized and can often be verified by contacting Morris Guitars directly. 3. Using Model Numbers to Estimate Age
If the serial number is missing or unreadable, the model number can provide a range:
The "W" and "M" Series: Standard dreadnoughts and 000-style guitars. A model like the " Go to product viewer dialog for this item. " likely cost 40,000 Yen when new.
Production Shifts: Morris guitars were primarily made in Japan from 1967–1980, then production shifted to Korea for mid-range models, before returning high-end production to Japan in 2001. 4. Expert & Catalog Resources
Because official databases are limited, comparing your guitar to old catalogs is often the most accurate method:
Catalog Archives: Sites like Vintage Japan Guitars host digital scans of Morris catalogs from 1970 through 1980.
Direct Inquiry: For modern instruments, you can download the latest official Morris Catalog PDF to check specs and serial formats for new series. Dave Doll's Pro Tips - Serialization and Registration

Title: Cracking the Code: Why Morris Guitar Serial Numbers Are a Folk Musician’s Treasure Map Note: Some use first two digits as year: 78xxxx = 1978
If you’ve ever held a vintage Morris guitar—perhaps a humble W-15 or a pristine B-50—you’ve likely flipped it over, squinted at the faded stamp on the neck block, and asked the same question: Where did you actually come from?
Unlike the linear, spreadsheet-friendly serial numbers of Martin or Gibson, Morris serial numbers are a wonderfully cryptic rabbit hole. And for the folk and bluegrass enthusiast, learning to read them isn't just nerdy trivia—it's the key to understanding one of the most underrated "lawsuit era" gems.
The Mystery of the 1970s "Black Label"
The most interesting part of the Morris story lives in the early 1970s. During the Japanese "lawsuit era," Morris guitars (made by the Moridaira Corporation) were so impeccably crafted that they rivaled Martin D-28s at a third of the price. Their serial numbers from this period are short—often just 4 to 6 digits—and utterly non-standardized. You might find a "3050" on a neck block and assume it's a low production number. Wrong. In many cases, the first digit indicates the year of the Japanese fiscal year, not the calendar year. A "3" could mean 1973... or late 1972.
This ambiguity is actually part of the charm. Veteran collectors have built entire forums around decoding these numbers through secondary features: the shape of the "M" logo, the type of tuning machines, or the infamous "Lawsuit" headstock shape. Your serial number isn't a receipt; it's a clue.
The Transition (Mid-80s to 90s)
As Morris moved away from Martin copies and into their own beautiful, asymmetrical designs (think the "Morris Fan-Fret" or the "B-500"), the serial numbers got smarter. By the late 80s, you typically see a six or seven-digit system: YYMMXXXX.
For example: 8704156
Suddenly, you aren't just looking at a number. You are looking at a birthdate. You know your guitar was built alongside the very first Takamines and Yamahas that would go on to dominate the world stage. It feels personal.
The "No Number" Phenomenon
Here is the most interesting (and frustrating) review point: Not all Morris guitars have useful serial numbers.
If you find a Morris with no serial number at all, or a blank stamp, do not assume it is a fake. During the late 70s export boom, Morris produced "seconds" and "store-brand" models (sold as "Conrad" or "Kingston") that were mechanically identical but lacked internal serialization to avoid brand-dilution. These "ghost" guitars often sound better than their numbered siblings because they were made by the same luthiers on a Friday afternoon with leftover premium woods.
The Verdict
Reviewing Morris serial numbers is not like reviewing a computer database. It is like reading faded calligraphy. You will not get a clean CSV export. You will get a headache, a magnifying glass, and eventually, a deep respect for a brand that prioritized craftsmanship over bureaucracy.
If you want to know the exact factory shift your D-18 copy was made? Buy a Martin. But if you want a story—a mystery that connects you to the hidden history of Japanese luthiery from 1972 to 1995—dig into those faded digits on a Morris. Just be prepared to argue with strangers on internet forums about what that "4" really means.
Rating: ⭐⭐⭐⭐ (4/5 – Fascinating and cryptic, but bring a cup of coffee and a lot of patience)
Morris guitar serial numbers are primarily found on the paper label inside the sound hole or stamped onto the neck block. While dating early 1960s to early 1970s models can be difficult due to non-standardized numbering, a consistent system was implemented in the mid-1970s. Serial Number Decoding Guide
Standard Mid-70s to Late-80s Format: Often consists of a letter followed by six digits.
Letter: Represents the month of manufacture (A = January, B = February, etc.).
First Two Digits: Typically indicate the year of manufacture (e.g., "81" for 1981).
Remaining Digits: Generally refer to the sequential production number.
Example: A serial number beginning with H81 would indicate a guitar made in August 1981.
Late-80s Onward: The initial month letter was often dropped, leaving only a numerical string where the first two digits still commonly indicate the year.
Early "Lawsuit Era" Models (Pre-1975): Serial numbers from this era (e.g., 1968–1972) are often 4 to 6 digits long and do not always follow a clear date-coded pattern, sometimes acting purely as sequential production markers. Identifying by Label and Construction
If the serial number is missing or ambiguous, use these characteristics to estimate the age: morris guitar - Guitarsite
Morris is a highly respected Japanese brand (manufactured mainly by the Moridaira factory, known for Tōkai and自家的 Morris). Their serial number systems changed over decades.
Format: Letter + 5 or 6 digits (e.g., M 860123)
Feature example:
Serial M 901234 → Morris, 1990, January 234th unit.
Note: There is no single, authoritative public serial-to-year table for Morris comparable to some major brands; most dating relies on community-compiled charts and comparisons to dated catalogs, ads, or paperwork.
