Here is a good link. Despite the link name, it lists most K bodies of all brands
Other brands with K-mount
KR-5 super 2 is the camera I most use out of my small collection- lightest and fully mechanical and not too old.
Tough war stories? It once fell 20 ft off a mezanine in a steel mill,
The nose of a push/pull zoom acted as a shock absorber and the body is undamaged.
There had to be a reason for those push/pull zooms, By the way I rebuilt the zoom too with parts from a dead one.
With nothing to lose, I corrected the registration of the lens by test shots so now that old zoom is quite sharp across the plane.
