Sears KS1000 SLR that works fine. It has a K to M42 adapter glued into the lens mount. Good meter and shutter. The Zenit 11 w/ case works. Now and again it will shutter cap a little on 1/500 but works fine below that. Viewfinder has a bit of separation in the center but it's easy to focus. These are a cheap way to shoot some M42 glass. $18 for both, $13 shipping within the US. US sale only please.
