Here is the picture:

That looks like M42 mount. This one allows full-aperture metering with some camera bodies (e.g. Spotmatic F).

Thank you, was not sure. Sometimes ebay can be a pain, people seem to leave out important details much of the time.

It looks very much like M42. Definitely cannot be K-mount.

Yep, can also tell from the shape of the body - the old super-tak!

Ahh I see, how much is a good K Mount to screw mount adapter go for? Is it best to go for the 30 dollar one on Pentaxs site? Also If I am out and about with K and Screw mount lenses, is it hard to go back and forth or is it just a quick screw on and off kinda deal?

Get the Pentax one, it's well worth the money. I've used two different non-Pentax adapters and also the genuine Pentax adapter and the Pentax one is much easier to remove. In fact, it's quite hard to remove the non-Pentax adapters without the tool that they supply. You only need to use your fingernail to remove the Pentax one.
If you get used to it, switching back and forth doesn't take that much more time vs switching a K-mount lens

thats good to know, didn't wanna pick a setup between them, good to know it becomes 2nd nature after a while.
