The 48B Conn-Queror was the trumpet model, while 48A was the same model with a cornet-size receiver. This rimless Vocabell (US patent no. 1,993,714, March 5, 1935) was scientifically graduated to permit maximum vibration in sympathy with the vibrating tone column in the instrument. The valves are constructed according to US patent 1,938,321 (December 5, 1933). The bottom valve caps follow US patent 1,956,254 (April 24, 1934). Valve casing and water key construction follow US patent 1,966,119 (July 10, 1934).
