Food for thought, I once had a Gibson Nashville-era Tobias Classic 5 string that was built by an employee who scavenged the parts out of the factory, completed the basses at home, and stamped his own serial numbers on it, passing it off as a "real" Tobias. Apparently, the body/neck had a slight cosmetic defect and it was set aside as a quality-control reject.
The employee periodically left work with various parts in his pocket, and completed several of these instruments at home, and sold them as used. The serial number on mine wasn't even on record with Tobias as a Classic 5, it was made up. I no longer have the bass, and made the buyer aware of its questionable history . . .
