Chris's camera pages
Made in the 'fifties by or for the David White Co. This is a fairly common stereo camera, and although it is really odd looking with the viewfinder and rangefinder windows at the bottom of the camera, it actually works quite well.
The lens cover doubles as a lens hood of sorts when in the open position. You can see the viewfinder window beween the the two taking lenses.
Here you can see the depth-of-field table on the underside of the lens cover.
