Conn Instruments, the trumpet appears to.
Conn trumpet serial number serial number#
^ Conn 16A Director late style with Olds Ambassador/conventional leadpipe wrap-made from 1978 ^ Note that the 18A, which first came out in 1980, was essentially a renamed late model 16A-the serial number system, the bell engraving, and leadpipe wrap were the same, with '18A' stamped on the mouthpiece reciever instead of '16A'. The valves are original with all valves stamped with the same serial number.
