Saxophone/C-Melody Grand Opera


I have a Stamped Conn, Grand Opera, silver nickel with a serial number that begins with P (P18020), not M. when I purchased it, I was told that it was in the U.S. military band that marched into Berlin, 1942. I can't find any info on Conn's with this type of serial number.

The "P" serial number is based on the Pan American line for Conn. During WWII it is possible that Conn was using up inventory as the factory was being converted over to be used for the war effort. The M series had rolled tone holes, P series did not. Same body dimensions, may have slightly different key work. Hope this helps.
