Nikon M, 1950
The second rangefinder focusing camera, while the format has shifted to a slightly larger format of 24mm x 34mm. Has a short run on production. Some Nikon historian stated production was probably began in 1949 but ended in December, 1950. Similar to the Nikon I in appearance (Similar Shutter speed range as well) except the Serial number began with “M XXXXXXX”. Early version has no flash synchronization but later version has it and some termed them as Nikon M Synchro. Virtually all standard production units were produced in silver-chrome. Some rare black versions were custom-made made for war photographers. A total of 1,643 cameras have been produced. The first from 08.1949 with serial number from 609759-609991 and changed number to 7 digits that begin from 6091098 in 1950; it ended with 6092401 in 12.1950. The rare numbers of both the Nikon 1 and Nikon M make both of these Nikon rangefinder models a difficult to source and incredibly expensive.
