22mm lens in OCT-18 mount for turret Konvas, #624013
Manufacturer of the optical block is unknown. May be LOMO, may be Zeiss.
Looks like some Frankenstein lens assembled of different parts since front part states that it has f/1.6 relative aperture, but aperture scale starts from T/3.2.
The lens has OCT-18 mount to fit 35mm movie camera Konvas (Automat, 1M, 7M), but it can be used with other cameras if your have an adapter.
T/3.5-16 (if the scale is correct), no clicks. Aperture control ring is decoupled from the diaphragm mechanism, some reapair required.
The lens has focusing mechanism, but no distance scale.
Glass has many tiny cleaning marks, but no fungus or deep scratches.
