Item No.: #5A199 This is a part removed from a Tokai TZ-65, which was manufactured for a short period in the mid-1980s. It has been cleaned and polished with polishing agents before listing, but not all dirt and grime has been completely removed. There are no screws that are stuck and cannot be turned, but as this is an old, used item, some screws may be difficult to turn. Please be careful when turning the screws during adjustments, etc.
