Conn 12i compact (3/4) euphonium. Very nice shape, a few small dents & dings. Lacquer is 95%+
Great doubling horn or for a smaller person, easy to hold and play. I've used these 3/4 euphoniums in pit orchestras where space is tight and I'm switching back and forth with trombone. Takes standard small shank trombone / euphonium mouthpieces.
This has a 4 digit serial number that makes no sense in Conn's numbering scheme but it can be dated between 1985 and 2000 based on the engraving and case badging.
