That's an SH-8 Invader bridge.
Value is a little more difficult since it's in pretty rough shape. You should be able to get $40 for it, but I wouldn't pay much more than that due to condition.
Wow, that was fast! Is there a way to tell how old it is? Thanks!!
I'm not 100% sure when the Invader was introduced, but they started using that type of sticker in the mid 80s or so. They stopped using that sticker in 2002, but no 'Seymour Duncan' on the pickup bobbin would date it to the earlier end of that range. I would venture a guess of late 80s or early 90s, but I don't think it's possible to know 100% for certain.
Why not sell it here?
