This page picks up from the previous one on Herrburger labels. Below, some shots of the stickers and stamps on the action of Jennings Univox J6 serial number 2037. The Univox action, as it turns out, is a Herrburger patent, applied for on behalf of the company by Leslie Astell on 18th June 1952.
The serial number on the body of the keyboard section, which has capacitors dated 1953 and later 1954, is 2037. "2346" is likely to be the number of the action assembly. "Style: NEW TYPE, SQUARE FRONT".
