The lens you had trouble with was indoubtably a PKA/R mount. The R part of the mount is indeed the flange that gets stuck in the Pentax power zoom contact. THe R prart, if I remember right, was created by Rioch when they adapted the K-mount to their camera's prior to the Pentax AF lenses and camera line.

may lock onto an MZ/ZX series body. I'm not sure how to identify these
lenses visually, but I understand it has something to do with a piece on
the lens getting stuck in a slot on the camera's lens mount meant for a
power zoom contact. Or something like that. Happened to me once when I
was demo'ing the great compatibility of Pentax's AF bodies with older
K-mount lenses. Oops.
