Please understand that while we may temporarily lower prices, we generally do not negotiate discounts. Management Number: #5A217 This item was removed from a Yamaha SB-500, manufactured from around 1977 to 1979. From a business perspective, parts were likely standardized as much as possible, so they are likely common with other models. Based on my review of catalogs, I believe they are shared with the following models manufactured around the same time (and may also have been included in other models manufactured around the same time): SB500/SB600/SB700/SB800 The item has been cleaned and polished with polishing agents before listing, but it is not completely free of dirt. There were no screws that were stuck and unable to be turned, but as this is an old, used item, some screws may be difficult to turn. Please be careful when turning screws during adjustments. For free shipping, the shipping method may be changed at our discretion.
