The 105 format was introduced by Kodak in 1898 for their first folding camera and was the original 6×9 cm format roll film. The 117 format was introduced by Kodak in 1900 for their first Brownie camera, the No.1 Brownie, 6×6 cm format. These formats used the same width film as 120 film, but with slightly different spools. The 105 spool has a much wider flange, similar to the 116 spool, while the 117 spool's flange is slightly narrower than the 120. The 105 and 620 spools also have much thinner flanges than the 117 and 120 spools ( vs. ); as a result, an unmodified 120 spool will not fit a camera designed for 105 film, such as a No. 1 Folding Pocket Kodak, as the overall length between the "outside" of the flanges is too long to fit the width of the film chamber.
