It looks to me that the marking to the right of f4 is 'KR' not 2.8 which would tend to confirm this is some third party lens for a Ricoh camera. You'll need to unscrew the mount and remove the little pin that you don't see on a Pentax mount (which otherwise tends to catch in a Pentax body's autofocus screwdriver recess and make the lens extremely difficult to get off the camera).

What's written around the ring surrounding of the front element, if anything. If Pentax, something will be written there. Also, A(P) on the aperture ring doesn't look to be Pentax. Focus looks to be the wrong way round as well. So me thinks not Pentax.
Just a wild guess, but does it have a Ricoh pin on the mount?
