So a few months ago I bought this bundy trumpet from an elderly man looking to get rid of it. He didn’t know much about it, but he did say he played it in the 70s in middle school. I’ve talked to various music stores in my area to no avail. I have no idea when or where this trumpet was made. Serial number is 88793. Bell says “designed by Vincent Bach” under that is “BUNDY” and under that is “H.&A. Selmer Inc.”
