Eastman Kodak 3A Folding Camera image
The 3A Folding Pocket Kodak, Eastman Kodak's first postcard format camera, was introduced in 1903 and sold until 1915. The image above shows a box of Kodak Verichrome Pan Six Exposure V122 film dated from 1944, an exposed roll of 122 film on an all-metal spool, and an early 122 film spool with the wooden core.  Later, film spools were made entirely of metal while earlier spools were made of both wood and metal. The F.P.K. Automatic Shutter was equipped with a pneumatic release. The original rubber hose and squeeze ball are still attached to the pneumatic cylinder in this picture. The shutter has one instantaneous speed plus time and bulb. The pneumatic release can prevent the camera from shaking when using the time and bulb settings. The rubber hose and bulb are removable but because of their size they could also be left permanently attached, as they do not interfere with closing the camera.
