For those of you who have never seen a real Gibson Loar era F5 FAKE this is one to study. It has the regular 1924 Master Model serial no. label complete with an unknown fake serial number. I would assume the signed Loar label fell out over the years OR this maybe one of those undocumented unsigned Loars that were seconds not worthy of Mr. Loars approval (Darryl W. and Ken W. know what I am talking about) from '24. Very interesting.................. Please note this is from a musical instrument dealer who seems to in the words of Sgt. Schultz of Hogan's Heros "I know nothing!!!!!" May the bidding begin!
