I was wondering which adaptor to use with this Ricoh lens .
I believe you'll need a K-mount adapter.
Even though the OP has obscured all the identifying markings on the lens I beleive you've got it in one.
Ricoh made a variant of the K mount which has an extra pin for aperture control. It's well known in Pentax circles as later screw drive autofocus linkages can catch on this (jambing the lens on the camera). From the P setting on the aperture ring I think this must be one of those, which match the k mount in all other respects. It won't be an issue for any of the adapters, as none of them support autofocus.
