Item No.: #5A061 This is a part removed from a Yamaha STH-500R, which was manufactured for a short period in the mid-1980s. Considering the business aspect, the parts should have been as standardized as possible, so it is believed that this part was also installed and used in other models manufactured around the same time. This is a single item (one piece) as shown in the photo. It has been cleaned and polished with polishing agents before listing, but it is not completely free of dirt, etc.
