Leica 0

Preproduction series of 31 cameras, Serial #100-130, hand-made in 1923 & 1924. Since the focal plane shutter was not self capping on the first seven examples, they required the use of a lens cap which was attached with a cord to a small bracket on the camera body. This feature was retained on the second batch even though they had a self-capping shutter. The viewfinder is located directly above the lens. (Image and data courtesy of Massimo Bertacchi)
