The trombone is in good condition with use to the lacquer. It is an excellent player with excellent slide compression, small sign of use to the base of the inner slide as can be seen in the photos. The hand holds appear chrome plated. Conn made this horn with out a bell wire, it is a rimless bell, its was advertised as having a mellow sound like a singing voice.3 small ding can be found on the upper area of the bell. The bore is .485 and take a shank a little smaller that a modern small. If the buyer needs a mouthpiece I can add one. The bell measures 7 inches.
The construction style is sort of Art Deck with the angled braces. Comes with a case in poor but solids condition.
