It's a J-48 or J-25 100/2, quite rare (and expensive!!) cine lens before OKS era. Those lenses were made by GOMZ, and give great image quality.

If no diaphragm, it's a cine-projection lens, can be J-48,J-25, and any other projection lens. Hand-made adopted on M39/M42. Now many OKS adopted on M42 presented on market, not cheap.

Why do you think there isn't any diaphragme? On the photos, it looks like there are two rings.
