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)

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 .

For certain export lines and specific mid-80s models like the or higher-end TF series , you may find a letter preceding the numbers.

The first two digits typically represent the year of manufacture.

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. YYXXXX

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)

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 .
