The Esco is a camera for 17x24 mm exposures on 35 mm film, made by Otto Seischab of Heideloffstraße in Nuremberg,[1] in about 1922. The camera body, which is metal and painted in a black crackle finish, is dominated by a magazine for 7.5 metres of film, sufficient for 400 exposures. The film is loaded by removing the base of the camera. The lens is a Steinheil Cassar 50 mm f/3.5, and the shutter a dial-set Compur with speeds 1 - 1/300 second, plus 'B' and 'T'. It has helical focusing. There is a folding frame finder on the top (which looks back-to-front, with the wide frame at the rear, and a centring aid at the front).
Seischab is not known for any other still cameras, but his company held patents for a design relating to film projectors.[1]
