This is a Fender licensed synchronized tremolo bridge. It was likely a model installed on the all-black Fender Japan Stratocaster (image ⑥, approx. ¥80,000) which was a limited edition model from around 2013. There is some rust on each saddle, but other than the saddles, it appears to be in good condition with a glossy finish. Measured, the mounting hole spacing is 56.5mm and the string spacing is 11.3mm as shown in image ⑦, so it should be compatible with bridges of the same size, such as GOTOH. [Included Items] ・Screws x 6 ・Springs x 3 ・Tremolo arm (cap is missing) ※ I will not lower the price in response to comments, so please purchase at the listed price if you are ready to buy.
