Mad-Mike No real way to tell, especially since Fender in more recent years out-sources some of that hardware from the same Asian companies making the reproduction hardware for other brands. If it's a vintage Fender, you can tell if it's an original 60's Fender or a Asian reproduction because the Fender bridges that came with original sixties offsets (Jaguar/Jazzmaster/Mustang) had rounded "rivet" holes over where the action adjustment screws for the bridge frame itself.
