Ear Trumpets (Ear Horns)

Black Brass London Dome Ear Trumpet (Ear Horn)

This black brass London dome is of average size. The ear tip is hard rubber (gutta percha). 

The manufacturer and date of manufacture is unknown, but it was probably produced somewhere around 1900.

This style of trumpet was named because of its similarity in shape to the dome on St. Paul’s Cathedral in London, England.

The design is a parabolic reflector into an ear tube which achieves considerable gain while maintaining a small size.

The dome of this ear trumpet is 3⅝" high and measures 2⅜" across the open end. The overall height of this ear trumpet is 4⅞".

The opening to the dome is covered by a brass plate with 2 rows of concentric holes—12 and 6 holes respectively—each 5/16" in diameter, and one hole in the center.
