Conn Brass Serial Numbers (rev.1)

This page contains a list of Conn serial numbers for brass instruments. That includes cornets, trumpets, horns, trombones, euphoniums and basses. This list is not correct for Conn saxophones (see Conn Woodwind Serial Numbers) or Conn bugles (see Pan American Brass Serial Numbers).

Revision 1
The widely available original Conn brass serial number list contains inaccuracies in serial numbers earlier than approximately 1920. This revised serial number list is the result of research comparing serial numbers with patent number dates, known historical events and dates on Conn Guarantee Bonds issued with new instruments.

This list undoubtedly still contains errors. If you own a Conn Guarantee Bond I would appreciate it if you could scan it and e-mail it to me. I am interested in comparing the exact serial number and date.

A few remarks
Some instruments, mostly from the 1920's, have either a star ("*") or the letter "B" stamped near the serial number. Current thinking is that these marks indicate a non-standard alloy, probably only of the bell. The suspicion is that a star indicates a gold brass bell (higher copper content), while a "B" indicates a "French brass" bell. None of this is confirmed at the moment (July 2009). Serial numbers with a "V" engraved after the serial number are factory seconds.
