Unknown. This camera has only USAAF numbers and markings. The K-series camera appears to have been the model of aerial camera favoured by the USAAF during the interwar period 1920-1942 Aerial photography has been used "for mapping, charting of the sea coasts, building of highways, town planning and any ground activity where a measure of size or change must be made. Aerial photography provided the first true measure of the size and physical makeup of the surface of Canada. It has played a vital role in major engineering developments such as the Trans-Canada Highway and the St. Lawrence Seaway. Aerial photography proved invaluable in the opening of the North and in the evaluation of Canada's forest resources."

Fonction

Aerial photography.

Technique

When the US entered WW2, the K-3 (Graflex/Fairchild) was replaced by the improved K-17 model. The K-17 has a shorter focal length than later cameras and was used for lower altitude reconnaissance in faster fighter aircraft (e.g. P-38). It appears that most of the patents found on the camera were assigned to the Fairchild Aviation Corp.; however, both Graflex and Fairchild built these cameras.
