This is a 6-way bridge for a Telecaster, likely a Gotoh GTC201, removed from a component guitar I purchased used. To confirm, I shaved a small, inconspicuous area that wouldn't affect playability. The material appears to be brass for both the bridge and saddles, and the machining quality is good, so I think it's probably correct. However, I'm not an expert, so please consider it as a "maybe it's a Gotoh" situation. Since the manufacturer is unknown, please consider this carefully. The screw holes and dimensions are the same as the GTC201, so please refer to those specifications. String spacing: 10.8 Includes 4 screws. There is some hand oil staining, which I will clean as much as possible. Thank you. GTC201 Gotoh Saddle Brass Saddle, Brass Bridge Telecaster 6-way
