Vocabell is a model name from Conn, like Director, Connstellation, etc. The Vocabell trumpets have a light weight bell without a rim ring. Conn claimed that this made the bell ring free and adds up to 15 decibells of sound over a the same horn with a bell. The styling is different than any other trumpet of its era or since, true art deco at its best. These were pro level horns. I think Conn's claim of more sound and a free ringing bell are true. They are great lead horns but would stand out in a classic horn section.
