I was out shooting this morning with a Honeywell Pentax Spotmatic, w 55/1.4 Mamiya Sekor. The camera body has a "Passed" sticker that says 1982. Were spotties still made in 1982? If so, when was the last screw mount spottie made?
That number on the JCII sticker is definitely not the year your camera was made.
A later model, the Spotmatic F, is the final model in the line. It was discontinued in
the mid-1970's, when Pentax introduced the K series cameras with bayonet mount.
