This is a Mastery Bridge M1. It's made in the USA and is for inch-standard guitars. I had it installed on a vintage Jaguar for a while, but I removed it and have been carefully storing it. There are no noticeable scratches or stains, and I think it's in relatively good condition. Please refer to the images for details on the included accessories. ~The following is from the manufacturer's website~ This bridge can be installed on JAZZMASTER®, JAGUAR®, and MUSTANG® type models. It's a model made in the USA to inch standards (thimble inner diameter .310 inches). It can be installed directly on current USA models and vintage models without any body modification. #offset #offset #jaguar #jaguar #jazzmaster #jazzmaster
