Morris Guitar Serial Numbers — Research Paper

Era 3: The Moridaira Corporate Era (1985 – 2000)

Morris Musical Instrument Co. formally restructured under Moridaira. During this period, serial numbers became less standardized, often just a batch number. Many guitars from this era have no serial number at all (only a model stamp).

Serial Number Format: 6 digits only (No letter, no model number prefix) Example: 345678

How to read it (tentative):

• First two digits = Year of production.
• The remaining four digits = Unit number.
• 92xxxx = 1992
• 95xxxx = 1995
• 98xxxx = 1998

Beware: A six-digit number starting with "0" (e.g., 012345) is likely a 1990 or 2000 guitar. Without factory records, these can be off by ±2 years.

3.2. The "Old Timer" Series

The "Old Timer" series (Madison, etc.) is a specific subset. These instruments often have a paper label inside the soundhole. morris guitar serial numbers

• Yellow/Orange Labels: Typically denote earlier production (early-to-mid 70s).
• Black/Silver or White Labels: Typically denote later production (late 70s to early 80s).

Era 1: The "Lawsuit Era" (1970 – 1979)

This is the most desirable era. These guitars were designed to directly compete with Martin D-28s, D-18s, and Gibson J-45s. They feature solid tops, Brazilian rosewood (early 70s) or Indian rosewood (mid 70s), and dovetail neck joints.

Serial Number Format: Model Number + 5 or 6 digit number Example: W-50 51234

How to read it:

• The first 1 or 2 digits of the numeric portion indicate the year of the 1970s.
• A "4" as the first digit = 1974
• A "5" as the first digit = 1975
• A "6" as the first digit = 1976
• A "7" as the first digit = 1977
• A "8" as the first digit = 1978
• A "9" as the first digit = 1979

Important caveat: If the first digit is a "0" or "1", you are likely looking at a 1980s guitar (see next era). Morris Guitar Serial Numbers — Research Paper Era

Example: Serial W-50 81234 = 1978 Morris W-50.

✅ Summary Table

| 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.

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 First two digits = Year of production

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.

⚠️ Important Notes

• No master list exists – Moridaira did not publish serial number logs.
• Reissues (e.g., Morris W-50, W-100) use modern serials but vintage specs.
• Custom Shop instruments often have CS + year + number (e.g., CS95-027 = 1995).
• Morris banjos/mandolins use a different, often unlabeled system.

5. Case Studies

• Example A: Morris W-40 (1978) — serial 784321 (numeric); matched to catalog image and Mexican-import paperwork; construction and headstock logo match Matsumoku period features.
• Example B: Morris M-700 (early 1980s) — alphanumeric M82-045; internal label and bridge design correspond to other M-prefixed serials linked by collectors to a specific distributor.
