The Tromhorn had the tube length and bore size of a tenor trombone, but wrapped in the appearance of a baritone. It was intended to serve as a replacement for the valve trombone in concert and marching bands. The Tromhorn was seemingly based on the King Trombonium produced by H.N. White and was produced from the mid-late 1950s through Reynolds’ last few years at the Cleveland factory.
