Morris Guitar Serial Numbers

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.

Morris guitars hold a revered place in the history of Japanese filmmaking—not cinema, but the absolute artistry of acoustic luthiery. Founded in 1967 by Toshio Moridaira, the Moridaira Manufacturing Company produced some of the finest acoustic and acoustic-electric guitars of the "Lawsuit Era" and beyond.

Pre-1975 Morris guitars often used laminate woods for budget models, transitioning to solid tops on models numbered 40 or 50 and above (e.g., W-50).
