Please understand that while we may temporarily lower prices, we generally do not respond to price negotiations. Management Number: #5A363 This is a removed part from a Yamaha SC-2C manufactured in the 1960s-70s. Considering the business aspect, parts should have been standardized as much 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) for sale as shown in the photos. We have cleaned and polished it with polishing agents before listing, but the dirt may not be completely removed. For free shipping, we may change the shipping method at our discretion.
