I love rangefinder cameras and have owned and used quite a few over the years including the C44. My favorite will remain the odd little Mercury II [0] with its movie camera style shutter and half frame format, it just took amazing photos and is a very robust camera in every way that is simple to work on with no specialty tools or micro surgery required.
Looking at the photos, that calculator wheel on the back looks wonderful. Certainly better than the contemporary paper calculator wheel that I got with my Argus.
It is really great and always where you need it. The shutter on these things is amazing and solves all problems with leaf shutters, filth has little effect on it and even if it gets dirty enough to inhibit function you can just open the back of the camera and click the shutter and stop its rotation with your finger so you can clean it, it is like 1/16" thick steel so you are not going to hurt it unless you actively try. The only real problem with the shutter is the spring will need replacing every 10k photos or so, but that is a simple matter and even if you ignore it all that happens is that the shutter speed is slightly slower than it should be. This camera convinced me that leaf shutters should not exist.
