Tenor trombone. Nominal pitch: B♭.
Technical description: Silver-plated brass. Inner slides silver-plated, with stockings. Spring-loaded 'siphon' water-key on outer slide bow guard. With alternative tuning-slide for a different pitch standard. Repair History: Tuning-slide receivers on bell section have been shortened, but the legs of the shorter t-s have not been shortened to match, so it stops at c22mm short of full insertion. The limitation is a step in the proximal receiver at c62mm, the distal receiver is unrestricted (expanding to the bell).
