Keefer offered the "Stentor" Trumpet with "Swivel Slide Bb to A" in both, the 1922 and 1924 catalogs. The earlier catalog describes the instrument's features and capacities as follows: With its rotary-change from Bb to A, the "Stentor" offers every facility to the player who takes both band and orchestra engagements, and its anti-friction-metal-lined valve casings, needle-spring-steel-poised phosphore-bronze pumps and perfection of workmanship afford the soloist every resource of virtuosity.
