I remember somebody pointing out that the K1000 is basically a Spotmatic SP F. They share a lot of physical features (including that silly photoswitch for the light meter, which iirc no other Pentax has) and are functionally pretty much identical except for the K mount.
Question is, is the K1000 REALLY just an SP F inside with a new lens mount and body? If it is, it would seem a useful source of SP F parts. I suppose over its 25 year lifespan the K1000 evolved a lot inside, which might invalidate the commonality of parts. DJE
