Originally posted by 6BQ5 I bought a working Spotmatic F off of eBay and had Eric perform a CLA on it. You will end up with a camera that's better than mint!
There are plenty of nice Pentax Spotmatic F cameras around at good prices; Asahi or Honeywell, it's the same camera.
But you may look a long time before you find one in the original box, and you will pay a steep premium.
Unused (very unlikely BTW) or used, any mechanical camera of this age requires CLA i.e.
cleaning, lubrication and adjustment.
Instead of buying a cardboard box suggest you spend the extra money on having your camera serviced.
