Rikenon P lenses may have the pin; XR Rikenon lenses do not.

Actually it's the opposite; the camera (or your finger) must overcome the spring pressure holding them closed.
If the opening does not change size as you rotate the aperture ring you do have a problem,
either a broken spring or gummed-up blades...

That's what I thought.....but the appeture ring changes the metering when it's mounted on the body (ricoch kr-10) when I rotate it.
