This is a tremolo arm removed from a Fender Japan Jazzmaster. I've been using it for a long time, so I don't think there are any problems. I'm not quite sure about the arm lock function, so I haven't used it. I don't know the exact year, but it's an old one. There are quite a few scratches and scuffs. There are also some areas where the plating has peeled off a bit (images 9 and 10). I don't see any rust, but I might have missed something. I will disassemble it as shown in image 1 for shipping. Only the parts in the image will be included. The green sheet and ruler are not included. For those who understand used guitar parts, and are willing to trade with no claims, no returns, and no cancellations, thank you.
