Our Aunt brought over our late uncle's old cornet. It is in very good shape for its age, but all it says on it is Philharmonic on the bell. No mention of the manufacturer on the case but there is a card in the case from the DEG company. The darn thing plays rather well and came is a Bach Mt. Vernon 7. That is very fine mouthpiece and it is in really good shape too. Anyone have any knowledge of this cornet and who may have made it? I am guessing it is maybe 50 years old. Rich T.
