1938 Leitz 3.5cm f/3.5 Elmar with feet scale and later caps. In M39 screw mount of course.
The glass has some haze in it. The lens has a wonderful patina with some pitting of the plating and the focusing tab is slightly bent as many are. These issues can be seen in the photos.
They would not prevent satisfactory usage of the lens. The focusing tab could be easily straightened out during CLA or just leave it the way it is and let the lens have its history. The lens was tested on a llf Leica and despite the haze, it performs, see the photos. It is expired film but the details are sharp.
