The Imperial Delta is a plastic camera made in Chicago by Imperial Camera and introduced in 1964. The Delta takes 4x4cm (1.57x1.57 inches) images on 127 film. The dark grey camera is almost similar to the Official Girl Scout Camera for Brownie Scouts which is beige with brown controls. It is also the older brother to the Imperial Deltex camera that employs the flash-cube instead of the two post flash unit. Both cameras have a simple single speed ever-ready shutter. The Delta has an option of a bulb flash unit that attaches on the camera top. The Imperial Delta was delivered in a modern camera kit package with a flash unit, the camera version for Brownie Girl Scouts was sold in a shoebox-like package also with a flash unit (Imperial Flash II) in brown color.
