A compact field cipher machine in an olive drab green wrinkle painted metal box, six pin wheels in a row along the top with movable pins around their rims, each wheel rim engraved with a ring of capital letters, a drum of sliding lugs behind the wheels, a folding hand crank at the right side, a small printing wheel with a narrow paper strip at the left, a letter counter on top, a data plate on the lid reading "Converter M-209", the lid hinged open, the machine on a folding field table, a single lamp from above at an angle, green paint and bare steel catching the light, canvas and darkness behind.
