The only differences between this and its famous sibling the 38B are a conical bore and a receiver that takes a cornet mouthpiece shank. Circa 1958, this long model cornet made famous by Thad Jones is in MINT CONDITION! We really do mean mint. Zero wear, zero dings, zero scratches. Includes original two-tone leather hard case - also in excellent condition - and mouthpiece. A rare find!
