Weird Lens won't mount

So I bought a random cheap lens from KEH, but I can't get it to mount on my camera, it seems to have the same bayonet tabs as my other k-mount lenses but has a much larger wall thing inside of the apature lever (it is there for like 90 degrees of the lens).

It also has a P setting not an A setting and the mount is labeled R/K.

I think I'm just going to cover the back of the lens very well and dremel off the little wall (because I'm pretty sure that it is what is keeping the lens from mounting) but if its not even a k-mount lens than I should just send it back and get a refund.

So I dremeled it off, it works just fine now, although whatever P is its not A the lens only works in M mode.

It is a clever little lens, it has 4 rings, focus, zoom, f-stop, and macro.....the macro feature is literally a built in extension tube, all it does is slide the whole lens away from the camera, very smart it seems like more lenes could do this.

The other two rings are a little more annoying, it only stops down in whole stop steps (which matters sorta), and has a very short focus throw.....a little less than a quarter turn. Now I just have to see how it performs, at the very least its fast for an old zoom.....its a 2.5-3.5 35-70mm

Looks to be a Ricoh/ K mount lens. P may be for program so be aware that there may be a small pin that jams up to the focus driveshaft and may make it hard to remove (you would probably have nooticed by now ). Some lenses have the flange in the way of the new design of the mirrorbox as you also found out. No big deal...
Bet it this one but in K mount......

Looks like a beauty! Makinon made a 24-50mm f3.5-4.5 of similar 4 ring control. It was dented and I couldn't quite justify purchasing it. It would look really nice on dslr though. It's mechnical presence would outimpress many of today's lenses. =P
