The first die-cast Leica camera (1933/1934): this prototype represents the earliest experimental version of the later Leica IIIc – with opening swing-up backdoor and folding rewind crank – features that were commercially introduced later in 1954 with the Leica M3, and in 1967 with the Leica M4. This camera will be part of the next Wetzlar Camera Auctions on October 12, 2024.
