At a practice today, the drummer had me look at an old Conn. I thought it was an alto but I took it to my tech who, after a closer look, deemed it to be a probable C melody. The serial #89924 has a C above it & a L below it. His book showed it was from 1924, possibly New Wonder or Transitional. The neck looks like a long alto neck with micro tuner & the body looks like an alto with a longer bell. It has rolled tone holes. I would appreciate some help with the I.D.
