Here is an early Leica 5cm f2 Summicron Collapsible L39 screw mount Lens in chrome finish with the radioactive thorium type "yellow optics".  The lens serial number is 1022108.
It is for the Leica screw mount rangefinder camera and also can be use with an adapter to put on many other digital cameras.
It is in Excellent- condition and shown with normal signs of use.
There are couple of dings shown on the top edge of the front filter rim, but a filter can be easily screw in without any problem. The rest of the lens finish are very nice and clean.

The optics are pretty clean in and out except for the front optic which shown lots of scratches marks, otherwise there are no haze or fungus. I only see a few tinny air bubbles inside the optic which is quite normal for these early lenses of this age and the mid and rear lens optics are very clean with no issue.
The lens blades are dry and clean shown with no oil on them.
It focuses smooth but on a bit on the tight side and the aperture clicks stop are crisp.

I have tested it on my digital camera and the images quality came out are little bit soft but still pretty good as is.
Because of the front lens condition, I'm selling it AS IS for parts only with no return.
Please make sure you totally understand this is a final sale with no return before your purchase.
It comes with a Leica chrome metal front cap and a black deep rear cap only.
