Leica's scarce self-timer Barnack — the IIId, coupled RF, 39mm screw, cloth shutter, 1940.
The Leica IIId was a short-run wartime-era Barnack body produced from around 1940, combining the slow-speed capability of the III series with a self-timer. Very few were made, which makes it one of the scarcer screw-mount Leicas in the line.
It is a 35mm coupled-rangefinder camera taking 39mm screw-thread lenses, with a horizontal-travel cloth focal-plane shutter, front slow-speed dial and an added self-timer. Focusing and framing use separate rangefinder and viewfinder windows, there is no built-in meter, and the shutter is fully mechanical and needs no battery.
It suits collectors of pre-war and wartime Leicas and photographers who want the III mechanism with a self-timer. In use it handles like other screw Leicas: quiet, compact, and reliant on the two-window focusing and framing workflow.
Because production was small, verify originality and serial-era details carefully. Check rangefinder patch contrast and vertical alignment, test slow speeds and the self-timer, and inspect the cloth curtains for pinholes and capping. Confirm finder clarity in both windows and smooth film transport.
