The earliest Matsumoku SG copies appear to have been introduced in 1970 or 1971. They used various numbers instead of names for each model, and the numbers were different depending on the brand they were building for, although specifications were mostly the same. This page covers Aria, Greco, Westminster and Fantom models.
Note: Serial numbers on these models cannot be used for dating.
