Need your help folks. Anyone have info they could provide me about this horn please? Besson Bugle, copper with 3 brass fittings, a very small mouthpiece chained to the horn. Stamped on the bell as follows: Besson & Co. London W.C.2 H.75983 (above the words is a symbol which looks like a crown sitting over the word KING...hard to tell if that is the word) It was purchased in the early 1980s in a Thieves Market near Bombay, India (today called Mumbai). Just wondering.
