Kowa 1:1.9/50mm newest for M39 | Vintage lens

This lens comes from a Kowa SE newest, a japanese camera from the Sixties. The lens was fixed onto the camera. To make it usable as an interchangeable lens, i had to remove and rebuild some parts.
Now the lens has a M39 thread mount and can be used on a modern digital camera via a M39 adapter. You set the focus and the aperture, the camera takes care of the correct shutter speed.
The M39 thread and the rear part of the lens are made of 3D printed plastic.
The lens will not work on a classic analogue rangefinder.

What's in the box: Lens on M39 thread.
