This instrument was built in Dresdon, Germany sometime after World War I (1918), and has two unique features. The valves are rotary valves, which rotate from side to side when the valve lever is pressed. This is different from the piston valves that you see on the cornets. Also, the bell is a ‘kranz bell,’ which means there is a second sheet of metal (in this case, German silver) that is added to the bell for reinforcement and decoration around the rim. This kind of trumpet would have a darker, more rounded sound than a modern piston trumpet, and was favored by musicians in both orchestras and bands.
3 rotary valves
