Please understand that while we may temporarily lower prices, we generally do not respond to price negotiations. Management Number: #5A324 This is a part removed from a Yamaha SX-60 manufactured in the 1970s. Considering the business aspect, parts should have been standardized as much as possible, so it is likely to be a common part with other models. Based on my confirmation using catalogs, it appears to be common with the following models manufactured around the same time. (In addition, it may also have been installed/used in other models manufactured around the same time.) SG30A/SG35A/SG50/SG70/SG90 SX60/SX80/SX125 We have cleaned and polished the item 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.
