Can anyone confirm what mount this is?

Hi. Was looking a cheap lens "R M C TOKINA TELE - AUTO 1:6.3 f=400mm" which seller thinks its PK but is not sure.

I tried to compare the photo with some lenses I have it looks similar but I'm not convinced its the same - especially looking at aperture levers. What do you think is it PK?

Olympus OM. The O/OM on the lens base is the giveaway.

Well, that and the two opposite buttons: One is lens release, the other is aperture stopdown. This base is very simple to chop to fit a Pentax mount. It takes me 5 minutes with a Dremel, including putting the board across my bathroom sink (workshop) and blowing away the dust when done.

Ahhhh.... I saw the letters but could not decide what they said - now it all makes sense.

Thanks you very much!
