Re: Lovely Conn Alto with weird 'A' in serial number
Depending on the format of where the A is located it may not be anything abnormal.
If the A is by itself it just the Alto desegnator nothing else.
If you could take a good picture of the Serial number area and post it or type the exact area with all spaces and lines someone should be able to help.
If it a 30's - 50's conn it should be a good player.
I play a 1937 Conn 6m viii that was refinished by well meaning parents. It looks nice but not original but it is a hell of a players horn. Horns were ment to be played so there is always value there.
Some of that era Conns were a PIA to get the bottom register to play right. Not a major problem since not used that much.
