The No 3A Signal Corps Model K-3 is a military version of the No 3A Autographic Kodak Special, made for the U.S. Signal Corps.

It has smooth brown leather covering, tan bellows and gunmetal fittings. The tan leather bellows in good order, with minor staining and edge wear. The leather covering is in good condition, with the only significant damage being to the bottom right rounded edge where the leather is scuffed. There are some marks and scrapes on the gun metal finish, especially at the base of the lens standard.

The camera is serialised on the front, embossed into leather as "K3 No 13", and also on the roundel on the inside of the lens board.

The shutter is loose on its mounting and will slide from side to side by a millimetre or so - unclear why, but does not affect display.


According to McKeown, only 100 of these were made and it is described as rare.
