I am selling a 1953 Olds Super Trombone. It is a .485/.500 bore with a 7" bell. The original owner I got it from bought it brand new and it has been in storage since the early 1960's in the original Conn case that is included and an original Getzon mouthpiece (also included). The inner slides have no wear and is still very smooth. 95 percent of the laquer is still there and any wear is in usual holding spots.
