Vintage Bob Mario Custom Clarinet Mouthpiece on French Blank - Measures .045

This is a cool old Bob Mario custom clarinet mouthpiece. Made on a French blank (maybe Chedeville? I can't confirm), this piece has Bob's name lightly etched in it, and “Classic Curve” just above that. He stamped it a .045” and it still measures true. Bob was a studio musician in Hollywood back in the day, worked on and made pieces for a lot of players in the area, but you don't see them pop up for sale very often. A neat vintage piece.
