There is no serial number engraved on the back of the headstock, but it is believed to be from a period when serial numbers and the use of parts on Japanese guitars were not standardized and underwent many changes. The manufacturing numbers on the rear and front pickups are from January 1976, suggesting that they were made by Nisshin Onpa (MAXON). The guitar body is believed to be a model from the mid-1970s, manufactured by Fujigen. One of the screws on the 4th string tuner is embedded in the body. Only the jack has been replaced, and the other parts are original. As it is an old model, there are scratches and dents.
