Hello all...great site! I have inherited my father's Benge trumpet which he bought in the mid 60's. It has "ML" stamped on the second valve and the serial number is 3149. It has a few small dings and some tarnish, but all the parts are free moving. I would appreciate any info you all might provide on this horn. I also have another trumpet (that he played in the Navy Band in WWII) and a cornet. But they are still at his house so I can't post their particulars just now. Thanks!
