Ear Trumpets (Ear Horns)

Cow Hearing Horn (Ear Trumpet)

This early cow hearing horn ear trumpet probably dates from around 1850 or so. There are no manufacturer's marks on it.

It measures 9" long and 2 3/16" in diameter (22.8 x 5.7 cm). It is very light for its size, weighing only 1.4 oz. (40 g).

This cow hearing horn consists of 5 pieces—a piece of brass-plated tin to extend the bell end, the cow horn itself, another brass-plated piece of tin to extend the tip end, a tin fitting to join the brass-plated tip piece to the ear tip, and a porcelain ear tip.

This cow hearing horn would have been quite attractive when it was new before the brass plating began to corrode.

As was common years ago, a ring was used so you could thread a lanyard through it. That way when you were not using the cow hearing horn it would be close by—hanging around your neck on the lanyard.

Close-up view of the ear tip of the cow hearing horn. The ear tip was made of white porcelain. It seems like it was glued into the metal fitting. Porcelain ear tips were used on very early ear trumpets.
