This is a genuine 2023 Fender American Performer Mustang 9.5" radius floating bridge in mint condition with the 52mm (2-1/16") modern narrow string spacing. As opposed to the wider original 56mm vintage spacing. Visually this looks like the current production American Professional Jazzmaster/Jaguar 9.5 Mustang style bridge but it is metric (despite being from an American model) and not standard (which you will immediately be able to tell if you use a standard size adjustment wrench vs the included metric one). This is a great cheaper alternative if you wanted the specs of the American Professional version but didn't want to pay nearly twice the price.
