This is an ABR-1 bridge, likely a TUSQ saddle, removed from a vintage 335 from the 70s. Details are unknown, but as you can see in the photos, it has aged nicely. At first, I thought it was nylon, but it's hard, so I believe it's TUSQ. Everything in the photos is included. The main body is nickel, but the height adjustment washers are chrome for some reason. I think it's in good condition and usable, but it's a used item with a history of use, so please understand the condition and ask any questions you may have.
