A Leica IIIc converted to IIIf. This camera was originally manufactured as a IIIc during the war in 1940 and was later upgraded to IIIf specification after the war. Overseas, such examples are often referred to as factory conversions.
The serial number is in the 360,000 range. The top plate, base plate, metal eyepiece, and shutter speed dial are inherited from the original IIIc, while the coarser-pattern vulcanite covering, the area around the shutter speed dial, and the rewind knob with film speed index reflect IIIf specifications.
This particular camera bears the N-L marking stamped between the D.R.P. and Ernst Leitz engravings on the top cover. N-L stands for Netherlands and is believed to indicate a camera handled by the official Dutch dealer Odin. As a comparable example, the S-T marking used by the French official dealer Tiranty is also well known.
In addition, this camera retains the original red shutter curtains from its IIIc days. Red curtains are often found to be heavily deteriorated and frequently require replacement during servicing. Fortunately, the curtains on this example are in good condition and remain usable, allowing them to be preserved during the overhaul.
A fully usable IIIc converted to IIIf with original red curtains and the N-L marking. This is a truly rare and special example.

There are numerous small scratches and scuffs throughout the body, showing heavy signs of use. This camera was clearly well used over many years.
It was fully overhauled in December 2025, and all operations are now very smooth. The red shutter curtains run crisply and decisively. The viewfinder is clear, with strong contrast in the rangefinder double image.
Maintenance has been thoroughly carried out, and it retains the high level of functionality expected of a well-sorted IIIf. A slightly unconventional piece—enjoy shooting with it to the fullest.
