Zenith "Crusader" [Mod II] Transistor (Body) Hearing Aid

The Zenith "Crusader" [Mod II] Transistor Hearing Aid was manufactured by the Hearing Aid Division of the Zenith Radio Corp. beginning in December, 1958. It was an 4-transistor aid. This was the second modification of the Zenith "Crusader".

The Zenith "Crusader" [Mod II] measured 2" x 1⅜" x ⅝" thick, and weighed 1˝ oz. with battery. The case was  gold-colored anodized aluminum.

The vertical rectangular microphone grill was in the front center of the case with the Zenith crest in the center.

The Mod II had the word "ZENITH" in slanting letters in the bottom right corner and two horizontal lines (both horizontally and vertically emanating from the bottom left corner.

Here is a blurb about the Zenith Crusader (Mod II] hearing aid showing its suggested retail price was $185.00 back in 1958.
