Silvertone Tenor Trombone, USA, Lacquered Brass with case/MP. Good condition, with wear/tarnish

Silvertone trombone. Probably made in USA. Comes with case and mouthpiece. Good playing condition, good physical condition, but with lots of wear/tarnish. The trombone has cosmetic wear/tarnish to the finish of the instrument and minor dings or small dents on the bell section from normal use. The tuning curve (on the bell section) moves easily. The main slide is undented and it glides with ease. The spit-valve key and slide-lock work. Case is old with worn exterior, but it protects the instrument well, and all three latches work. Serial # 155582. Free shipping to the continental U.S. (Ask for reduced shipping if you live in Mexico or Canada.)
