The laquer has been slowly peeling off my 1931Conn 2B New World Symphony trumpet ever since I bought it out of a pawn shop over 40 years ago and I have decided to drive laquer it down to raw brass. I was wondering about possibly having it gold washed because I like the look, however after browsing around here I discover that a gold finish mellows the tone so now I am more convinced than ever that if I can find a place to get it done ? And can afford it ? I would definitely like to have it gold washed .
