This is in very nice condition. Very clean and with only a few very subtle bright marks, as well as several small dings on the base plate (as pictured). The shutter appears to be in excellent condition and all functions working properly. Shutter fires at all settings, but I can not attest to the accuracy of the timings. Self timer works perfectly, and all knobs and film advance are very smooth. The vulkanit covering is also excellent. Personally, I find the IIIf and IIIc (which I'm also selling by the way) to be the most well designed of the Barnack rangefinders.
