YSL-681B Ian Bousfield Early Yamaha Model SN 001367. Is large bore tenor, .547, with 8.5" gold brass bell, standard weight straight bore .547 slide, yellow outer tubes, brass end crook. We did full shop service here, including chemical bath, rotor serviced, water key, minor service. Had a previous bell crease, not too bad, was a clean one, the lacquer is good, small scar not much. Still plays proper. Has fantastic slide and valve which makes it easier to overlook the prior bell crease. We think this horn is priced right for anyone looking for their first large bore open wrap trigger horn. Will include a nice mouthpiece. Has older style Protec. We put a new zipper tag on one side, it's fine. Interior was cleaned. Will not disappoint.
