Though the model run was from the early 30's to the late fifties, the models with the "Big B" engraving are considered to be the best of the bunch.At the end of WWII Buescher commemorated it with the production of the 400 line.Zephyr Specials and early Super 20's have elaborate engraving on the bell and keys, and pearls riveted to the key touches.
