1 NTN66 2 weeks ago I purchased a 1956 Jet Firebird yesterday from a local classified. Seller knew no history of the guitar. Her late husband inherited it when the guitarist in his band passed away years ago. Most items appear consistent with the 1956 serial number (minus a few replacement screws)The white pickups are a mystery to me (note extra screw hole). Anyone familiar with these as an option in ‘56? Any way to verify what they are and age?
