Benge Freelance 170 Tenor Trombone. A rare model, manufactured for only four years from 1986 to 1989. This model features an 8-inch 3B bell made of gold brass and a 2B+ (500 bore) slide. ※Same specifications as JJ Johnson's 3B. The lead pipe is a one-piece lead pipe, the same as those used until around 1974 (Vintage). There are only minor scratches, and the slide is smooth. It will be shipped in the original case from that time. Mouthpiece not included. -
