The Folding Rainbow Hawkeye No.2 Model C was made from 1930 to 1934 and used 120 Film. The Kodak 120 film cartridge (roll of film) came in two sizes. One had 12 exposures and cost 55 cents in 1930 and 6 exposures for 25 cents. The camera had four aperture settings numbered 1 (f5.6), 2 (f8), 3 (f11), and 4 (16). The Kodak lens assembly shutter speeds are T (timed) and 1/50 of a second and has the number 41968 embossed on the nameplate around the lens. The camera's small waist-high viewfinder is mounted to the top of the lens assembly and can be set for landscape or portrait position. On the fold-down slid bed are three markings for focus distances. One marked 8 feet or 2.5 meters, fixed 25 feet or 7.62 meters, and 100 feet or 30 meters. The 100 or 30-meter setting is also the infinity setting. The other features of the camera are a fold-down foot for setting the camera on a tabletop for portraits that also locks the camera when closed, small red window in the back of the camera for frame counting, winding key for advancing the film, leather carry handle, and two tripod sockets. Adding or removing film from the camera involved removal of the works of the camera to reveal the casing and the film spools at either end. The camera came in five colors of black, brown, green, Old Rose (pink) and blue with the black one having the least value today but all original sold for $8.00 in 1930.

There is also a pink "Old Rose" version, currently (17 Nov 2019) selling on Ebay (Pacific Rim cameras) with asking price US$180.
