Manufactured between 1938 and 1947 by Graflex, Inc. Like it’s bigger cousins but taking 2-1/4x3-1/4 images—a Speed Graphic in convenient travel size! (OK, not really, but if you were used to the 4x5 version, it would almost seem like a pocket camera.) All Speed Graphics have focal-plane shutters in the back. Almost like the Anniversay Graphic model, it has two focus knobs on the metal bed and chrome trim. The bed does not drop and the front does not shift side-to-side, only up and down. The sports finder is hinged, it has a tubular finder and a Kalart range finder. Shutter release and winding is on the side of the main camera body. It has what became known as the “2x3 graflock” back. On this example, a Kodak Ektar f/4.5 101mm lens set in a a Graphic/Kodak Flash Supermatic shutter (made by Eastman Kodak for Graflex). The shutter uses two springs—one for speeds of 1/25 to 1/400 of a second and one for 1 second to 1/10 of a second. The back shutter could be put on “T” and you could use the front shutter or the other way around.
