Up for sale is a vintage Conn 2H professional jazz trombone with Red Brass and Nickel. The serial # is 202.xxx which would put it at 1923. Please check out the pictures. It is in very good condition and has a slide lock. The finish is unlacquered and polished so the appearance is quite light.  Without polish, the appearance is red. It looks like the 12H and 18H, but Conn was not supposed to have the Coprion Bells until 1938. Insured ground shipping will be $59.  Continental USA buyers only please.
