You get a Leica 90mm f/4 Collapsible Elmar M. Catalog number 11131 and ILNOO. Leica caps are included. I have just had the lens serviced by YYE camera service. Beautiful cosmetic condition. No dings, dents or obvious use. The focus is in feet. Serial number 1188109 made in 1954 in Germany. The lens uses E39 filters. 

The glass has no fogging, haze, or scratches. The focus and diaphragm are smooth. No oil on the blades. There is some light coating wear near the outer edge of the glass on an interior element and minor dust. This has no affect on the image. The lens has been tested on a digital M and the image rendition is very good. I asked about the coating wear and it is just an age issue. 

It is hard to believe that this lens is 70 years old and produced in the first year of production.
