Vintage Ernst Leitz GmbH Wetzler Summicron f=5cm 1:2 Lens For Sale

Vintage Ernst Leitz GmbH Wetzler Summicron f=5cm 1:2 Lens
Condition is as shown in photos. It looks very nice however I have NO camera experience and have never even used a film camera....I found this at an estate sale and it was on a Leica M3 Camera which is also up for sale. It looks clean with NO mold or mildew that I can see with the naked eye. Please ask any questions and I will do my best to help., Sold as-is as shown with no returns.
