Argus introduced the "Argoflex Model" in 1950, but it was only offered for a few months. With minor cosmetic changes (including neckstrap lugs) the same camera became the Argoflex 40, and then the Argus 40.
This was an elaboration of the Argus seventy-five molded body, but adding a much better focusing f/4.5 anastigmat lens, plus shutter speeds variable from 1/25 to 1/150 and B. While the camera's picture-taking lens could be focused, the entire Seventy-Five family used a simple brilliant finder rather than reflex focusing; and hence the Argus 40 must be considered a Pseudo TLR.
