I recently bought a "MODIFIED" 1959 Freshman. All of the mods were done post factory, bridge Franz pickup, switch & wiring harness, B3 bigsby, etc... Mods look to have been done in the early 60's or with early 60's parts. But the label inside the guitar is the most puzzling. It's definitely looks original to the guitar but for the model it's just scribbled "STAR" and no serial number. Anyone ever seen one like this? Any ideas?
