In the late 1940s, located in the lower Sawyer Woolen Mill factory on lower Mill Street, was a company owned by the MARK BROTHERS, Isadore and Benjamin, part owners in the Keystone Manufacturing Co. in Boston. After WW II they begain producing roll film for medium format cameras and eventually smaller format 35mm film labeled as DOVER FILM. Even 16mm movie film became part of the inventory and shorts of Tom Mix, Charlie Chaplin, Little Rascals and children’s cartoons were released in coloful Dover Film packaging. These were from the Keystone Toy Company selling hand crank toy projectors. A company producing a Direct Positive Camera (Speed O Matic) failed and the Dover company purchased the molds and began producing a 620 roll film camera that produced 16 4.5 x 6cm images. The camera is equipped with a yellow filter for black & white scenics and a portrait filter mounted on the front. Camera instructions and exposure information was printed on a metal plate attached to the back of the camera. The lens has a built in rotary disc with five openings (f/stops) and the shutter is a single speed. Flash bulbs were used with a flash attachment built onto the camera with a removable reflector. The camera was packaged in a cardboard box with a colorful label attached to the front.
