Hello there! I have an "unknown" brand vintage baritone sax I am trying to get some information on. The history is slightly confusing... On the back of the horn it says the following: PATD SEPT 14, 1915 1154389 B 48882 L
if you have any info as to when this horn was made, who actually manufactured it, please let me know. I looked up the serial number and it could have been a Buescher or Selmer but there's no insignia for either of those companies on this horn.
Conn moved the bell keys to one side on their Bari saxes around 1930. so, yours is after that.
The upper line of instruments had a different brace from the bell to body, probably 12M on the back by the serial number. I included a picture of mine, which is right at that point in Conn's development. It looks to be in very good condition. If you decide to sell it, let us know and some of us will be interested enough to find any online listing you may place.
