129 film was a roll film format introduced in 1912 and discontinued by Kodak in 1951. Each roll produced eight 2-inch by 3-inch (approximately 5×8cm) exposures. This frame size puts this film between the frame sizes of 127 film and 120/620 film.
The 129 spool includes button tabs along the centerline of the spool that extend beyond the film flanges, similar to 127 film spools. The tab on one end of the spool has a wide slot that engages with the camera's winding mechanism.
This roll film size has the distinction of being the only size created by Kodak for which they never made a camera. The size was introduced by Kodak to provide film for the popular 2x3 folding and box cameras made by Ensign in England. Following introduction of the standardized Kodak size, many German camera manufacturers also produced cameras for this film size, particularly in the 1920s. Although Kodak stopped selling their own 129 film in 1951, European film manufacturers continued selling 129 film until at least the mid-1960s. Some sources identify a small British film manufacturer (Standard) that made film in this size until the mid 1970s.
This film size was also referred to as "E29" (Ensign) or simply "29" by film manufacturers other than Kodak.
