This is the Gotoh 1996T, a famous Floyd Rose-type bridge. The block is the standard 40mm length. This is a high-precision model from Gotoh, also used in high-end guitars like Suhr and James Tyler. It's hard to tell from the photos, but I believe it was Cosmo Black, with a slight gloss. I bought this as a spare and stored it for several years, but I'm selling it because I no longer have a guitar that I plan to use it on. I only installed it once to check the operation, so there is almost no damage to the studs or the plate. There is some deterioration of the plating and some scratches due to storage. It's difficult to see because it's black, but please understand. I cannot accept claims that it is different from what you expected. Gotoh's locking nuts were generally sold separately, so it is not included. The arm is also missing. Although not original, I will include three different wrenches that fit. Other included items are the spring hanger and screws, studs and anchors, and springs. The hanger and screws are not guaranteed to be original. Thank you for your consideration.
