It may be an Elmar. Is there any serial number on the front?

Very unusual knurling around the front ring, never seen a Leica lens with that pattern. The applied plate with the aperture numbers is also out of place. Wondering if this is a Russian Leica copy. Camera looks somewhat crude as well... |

I would ask the same question in the Leica-Forum (www.l-camera-forum.com); they have a specific section "Leica collectors & Historica".
My first thought was also "Russian Leica copy", but by no means I'm a Leica expert.

It isn't metric, says feet. So probably not German or Russian. Maybe early Japanese copy. There is a Serenar 50/3.5 from Canon. Are these your pics? How is the camera branded?

Elmar is just what Leitz called their Tessar.

At least they move the position of the aperture forward.

Although the Elmar is usually said to be a Tessar design, its a modification of the tessar, with the blades just behind the front element. Check where the blades are, that'll tell you definitely if it is an Elmar or not.
It doesnt look Russian though. The aperture sequence is pre-war, some Russian lenses had the same range. All the Japanese copiers of Leicas made their own versions of the Elmar: Canon, Minolta, Leotax, Nicca etc.
Puzzling

This is exactly what i though! From the photos above, it seems the aperture is right behind the front element.

The eBay item https://www.ebay.de/itm/384774194771 is NOT an interchangeable Leica lens. It is the lens removed from a fixed-lens Leica I camera, which was held on by screws, and was not rangefinder-coupled. It would also need to be collimated (calibrated for infinity focus) once mounted on a lens-less Leica I camera. |
