OK I dug up the info, It's a Solitel f2.8 135mm lens. Any idea what sort of mount it has, looks like a screw? M42?
Cheers

None of the M42 lenses I own have a thread on the cap.
It could simply be bad lighting & bad picture that's preventing us from seeing threads on the base of the lens.
The auto-aperture pin implies to me too that it's an M42 lens.
Or suggest something else it could be?
Screw it, why do I even bother posting on here any more.
