Slide trumpet, brass body, ferrules and garland. Clock spring slide return mechanism. Angled F shank, no other shanks or crooks. Mouthpiece presumed original. Undecorated.
A slide enables this trumpet to play chromatically. It is at the end of the instrument closest to the player and is drawn out towards the chin. A spring returns the slide. Despite the development of the valve, the slide trumpet was used in England during much of the 19th century. This is probably due to the high profile of Thomas Harper senior and junior, father and son, slide trumpet virtuosos.
