This Mandel is one of the street cameras that allowed a photographer to take and present to a customer a finished picture fairly quickly. This one is called a PDQ which may have meant Picture Done Quickly. The crank on the side moved the film down after the picture was snapped where the knob could be pulled that cut off a piece where it fell into the developing tank. Mine doesn't have the tank, I am sorry to say. Also the one minute glass timer on the side is not original.

These vintage Street Photographers Cameras sometimes used a acid monobath to process direct from an exposed paper negative, that was re-exposed to light and bleached to make positive, they were not washed and faded quite rapidly.
There were many variants to the method, number of chemicals etc, and whether just the negative was needed, with contact prints made separately on the spot.
Very messy, and the acid processes, (some were caustic), attacked the metal or wood tanks inside, which is why they are often missing. Some used glass tanks, they broke easily, again not surviving well.
The processes attacked the skin on the hands as well, very nasty stuff,

More Pre Polaroid. The Photo See. 1936. "Photos in 5 minutes." Separate Camera and developing tank. Not a raging success.    Mickey |
