Made from about 1917
The 3A was designed to make 3-1/4" x 5-1/2" exposures on Kodak's A122 film .
It was the first commercially produced camera to have a built-in coupled rangefinder.
This one has a Bauch and Lomb Tessar 11b in Kodamatic shutter.
Very good condition, complete with Stylus and leather case.
