Just got this one. 1959 production in screw mount. There is coating damage that is visible with a bright flashlight but based on these I'm not too worried. This was a simple run around the neighborhood to test the lens.
Out of my curiosity, these are all SOOC jpgs.
Got this at auction in July. It was part of a large Leica collection assembled by a gentleman over a lifetime. It seems he was more a collector than user as many of the items looked pristine such as this little beauty.
