Up in Teesside but may post, he does sell on ebay too (from our conversation while I was there) but no idea if this stuff is on there.
Had a bit more of a look at the lens on the K2, it has a wobbly front barrel, but also seems it won't stop down past about f8 - the aperture ring clicks but the aperture doesn't get any smaller. I have other lenses I can use to try the camera out, but looks like this will need a bit of attention. It's a Pentax 50mm f1.2 and looks like a nice piece of kit.
I'm looking at a couple of camera cases on ebay - they do still have cameras in them though! I might soon be able to do you a deal on a Nettar 6x6 without a case...
