I recently picked up this mint Asahi Pentax K circa 1958, from what I gather it was made for only one year. For base of reference this is an M42 screwmount body that looks like but pre dates the Spotmatic. It came with museum grade 55/1.8, 135/3.5 Takaumar lenses and an everready case. I paid $150 Canadian out the door for this set. Did I do well?
