What is "cine-kodak"

The Cine-Kodak was the first 16mm camera, introduced in 1923. It was a rectangular cast aluminum box approximately 8 inches square, and was cranked by hand at two turns per second to achieve the necessary 16 frames per second. Hand turning meant that a tripod was essential while allowing varying speeds and single frames to be taken. Accessories such as lenses and a motor attachment became available later. Production ceased in the mid 1930s. In 1925, Kodak followed up with a spring motor-driven Cine-Kodak Model B, at which time the original Cine-Kodak was re-designated as Model A.
