My copy is a bit of an anomaly. It is clearly marked "A2F" inside the body. However, on this example the exposure calculator on top of the camera is painted black with chrome numbers in a style that is typical of the post-war Argus A2B. The A2F was manufactured with a removable plunger button for the shutter, this copy has a regular trigger button, as seen on the original Argus A. Since there were so many different models in the A series, it's possible this model could have had parts replaced from other cameras in the series, or maybe it was manufactured using left-over parts in the Argus factory.
