Euphonium in B-flat

Description

This is a double-coiled, upright-bell euphonium made entirely of silver-plated brass, with a wide and conical bore, and four piston valves that make a four-valve compensating system (i.e. each of the main valves have two windway loops and the fourth valve brings its loop into the windway by passing through the three other valves; when used in combination, the main valves use the shorter loops for the windway). There are two water-keys: one on the first valve tuning slide, and the second on the main tuning slide. There is a fake bow tube just behind the pistons for the player's grip. The second and third valve tuning slides have a pull ring, and there's a latch for holding the fourth valve depressed. There's also a silver-plated mouthpiece. Nominal pitch: B-flat. This instrument is a British Army Pattern no. 6615.
