Ozeck mystery lens

Hi helpful people
My mother in law has somehow gotten an Ozeck 135mm f/3,5, with a odd mount. Cosmetically its near perfect, so I was hoping someone could help identifying the mount, and suggest how (if possible) to convert it to pentax.
Thanks in advance

This is the standard reference for ID'ing lens mounts.

I have an Opticam 135mm 2.8 that looks exactly like that !
It is a T2 mount, don't loosen the setscrews just unscrew the entire knurled base.
There will be threads on the end of the lens barrel.
I bought adapters to K mount from Fotodiox in USA, but they are available on Ebay from all over, they screw onto the lens and you will have a PK mount 135mm.
The setscrews are to allow the mount to be turned to align the markings when on the camera then left alone.
Does the lens have 15 aperture blades ?

Thanks alot Bobpur, I didn't realize that I could just unscrew the mount, which is an Olympus OM by the way. 10 aperture blades as far as I can count...
