|Film Size: 2 1/4 x 3 1/4" Plate
Shutter: Interesting manually-operated mechanism
Lens: Kodak Anastigmat 72mm f/6.3
|This is a
copy camera that was built for making 1:1 photographic copies of finger-print cards or
other 2 1/4" x 3 1/4" photos or documents. A lens is recessed inside
the flat-black rigid shroud and is pre-focused on the plane of the opening in the front of
the shroud. To make an exposure, the shroud opening is placed directly on the surface to
be photographed. Four battery-operated flashlight bulbs inside the shroud illuminate the
subject during exposure. One of the bulbs is barely visible in the first photo at the
lower right corner of the shroud opening.
The second photo shows the camera opened up. The left portion is the actual camera body, with the lens visible at the front. The shutter is simply a sliding lens cover that is moved out of the way when you press the shutter release lever, then is closed by a spring when the lever reaches the end of its travel. The actual exposure time is determined by how fast you move the lever.
The two brass parts on the left side of the lens are contacts that connect to the battery/light circuit in the shroud. The batteries are normally located in the vacant compartments in the shroud. When you press the shutter release lever, the circuit closes, turning on the flashlight lamps in the shroud. Synch? Well, the lamps come on just before the shutter opens, and remain on until you return the shutter lever to the closed position.
