Studio Cameras
The Century Camera Company was formed sometime around 1900. One reference suggests that that is where the name originates. Century is accredited with at least two basic designs. One being a handsome leather covered drop bed field camera and the other being a series of studio cameras and studio stands. Shortly after their beginning, George Eastman bought a large interest in the company which essentially gave him control. in 1907, the company began labeling cameras as " Century Camera Div. Eastman Kodak Company." Presumably, you could date your camera as pre 1907 or after by that information.I have one reference that suggests there was Folmer-Century Division of EKC which would have to have existed before 1926 when EKC sold off the Folmer & Schwing Department eventually becoming Graflex Inc. in 1945. In reference texts, the Century Studio camera line has been one of the least documented line of all of Kodak's cameras. I can only guess that there is little interest in collecting many of them because of their size. There is a swell of information on the internet requiring just a lit bit of searching.Explaining the letter designations after the models numbers.After the Century divestiture in 1928, Kodak continued the Studio Camera line. I saw a reference to a 1933 model 3A, through 3E Kodak line referring to the No. 3 camera in various packages or "Outfits" as well as two different size backs. The combinations varied by including the stand, the sliding back, and in 8x10 or 6½x8½ Format.I'm making an assumption that the letter designations refers to outfit variations in the number model."
