Cortiton Model TH Transistor (Body) Hearing Aid

This Cortiton Model TH transistor hearing aid was made by the Cortiton Hochoki Co. of Tokyo, Japan around 1963.

The Model TH measured 3" x 2" x ¾" (7.7 x 5.2 x 2.2 cm) and weighed 3.6 oz (104 g) without the battery. It had a light gold anodized aluminum case over a black plastic chassis.
