(solved)Pentax PK mount lens

I have an old ACCESS 58mm lens that I would like to use on my Pentax K-x camera. I believe it says it is a P/K lens mount. It kind of fits onto the camera body but it won't turn. Is there some kind of adapter I can get to make it fit?

It starts to turn onto the body but stops? Is this a K-R candidate? Can you see any tiny pins in the lens mounting, say just somewhere near the six o'clock position (if the red dot marking is at twelve o'clock)

No, I don't see any small pins. Here are some photos.

I should have phrased that differently. It won't turn but it will fit into the camera body but not fully into the 3 o clock side of the camera.

It looks like the flange that protects the aperture lever may be too large - some older Vivitar lenses have the same problem. If you have one, compare the flange on the mount to a Pentax made lens.

If the flange is the problem then your options are to cut it down or to unscrew and remove it, depending on how the lens is designed.

The flange that protects the aperture lever is your problem - compare it with any other PK lens. There are a number of illustrated threads here and on the PF showing how to correct this.
