Cased French Triple Ear Trumpet Set, Faux Tortoise Including Rare Early Battery-Operated Model This is a very rare cased set of 3 ear trumpets, all of faux tortoise shell (celluloid) composition, and all signed "Harrys, Paris", circa very early 20th century, or possibly late 19th century. One of the 3 devices is a most unusual, early battery-operated model, and the original battery is present. This battery-operated unit features a push-button electrical contact. Although I am not aware of another similar example, it is believed to operate using a carbon-type mechanism similar to those invented for telephones in the 1880's (see Historic Devices for Hearing, page 60), the first such mechanism employed in hearing aids.This triple trumpet set is contained in its original, fitted, 11.3"W x 7.3"D x 4.4"H wooden case. The case is covered with a dark green, grained cardboard covering, with decorative gold banding and signed "Reeducation Auditive, Harrys" in gold letters on the top. The case is closed with two decorative brass catches. The fitted interior is lined with green silk and blue-green velvet. T is a designed place for the original battery, which is secured with an elastic strap. The original 4.5 volt battery is a perfect fit for the electric device and bears an original label, reading "Pile Astre, Supporte Toutes Les Comparaisons.
