I received one of his trumpets yesterday in the mail, and guys it's really a nice trumpet, this one is Cocobolo with delrin mouth piece. It was oil soak and finished and the Cocobolo is just beautiful. It takes very little air draw, very easy to play and the bell opening is about 5/8 across with overall 1 1/4 inch outside to outside. Overall he makes a good hunting trumpet. Look him up on facebook and look at some of his trumpets. Cory Chustz, Baton Rouge Louisiana
