Please understand that while we may temporarily lower prices, we generally do not respond to price negotiations. Management Number: #5A219 This is a removed part from a Yamaha SB-600, manufactured from around 1977 to 1979. From a business perspective, parts were likely standardized as much as possible, so it's believed to be a common part with other models. Based on our review of catalogs, we believe it is compatible with the following models manufactured during the same period (and may also have been included in other models manufactured around the same time): SB500/SB600/SB700/SB800 We have cleaned and polished the item with polishing agents before listing, but it may not be completely free of dirt. While there were no screws that were stuck and unable to be turned, this is an old, used item, so some screws may be difficult to turn. Please be careful when turning screws during adjustments. For free shipping, we may change the shipping method at our discretion.
