This is a guitar tailpiece. The build quality is overwhelmingly superior to modern, inexpensive SG parts. Manufacturing period: Around 1977-1982 (almost certain) Material: Machined brass + nickel-based plating Genuine or OEM part for Japanese vintage SG guitars Regarding the precision and alignment of the string holes: • The holes are not perfectly aligned, with slight individual variations. • The chamfering after drilling is not perfect. • The depth and shape of all six holes are slightly uneven. This is typical of the pre-CNC era (manual jigs + drill press). It reflects the machining precision of around 1975-1982. ●Notes● ✤ We may overlook small scratches or blemishes.
