I think I remember Uwe with a 3 pup gold hardware 'Bird that was an original and a one-off, iirc, but for the age of this one those pups should be three screw fixings to be original...? Also the mix-and-match parts are a questionable feature...?
Yeah, I sold my 3PUP TBird stamped Prototype to Uwe....actually a Thunderbird VII, named after the Firebird 3 PUP model. The prototype was black with black PUPs and black hardware...and a Firebird stamped Pearl pickguard. The actual run of six of them were white ones and red ones, with gold two screw PUPs. Originally done in 1990-91.
The one on EBAY HAD BEEN MODDED BTW.
