I would concur, based on the shape of the cutaway, the tailpiece, and the one "speed" knob in view. It's pre 1957 vintage for sure (tailpiece became more ornate on the 57 models among other things). My guess would be 49-53 era. I wish I could see the pickup(s) that would really help. Additionally, you can see part of the f-hole below the pickguard. It's hollow. The only thing I don't know, is if dots or trapezoid fret board markers were used on 49-53 vintage 175's. Seems like a question for Jim R.
Any idea when that picture was taken? Whatever it is, it looks awfully small in Tal's hands.
He had huge hands.
