Film Spotmatic, too good, too common to be interesting?

the mirror stuck in the up position. I then read that this was a common problem with older Spotmatics, and my memories of developing B&W film and printing, I still have an enlarger and other equipment, but the return to film seemed almost impossible.

I have had quite a few Spotmatics, and never saw one with a stuck mirror, I have seen other slrs with stuck mirrors though. Environment has a lot to do with how well a camera ages, heat, humidity etc.. I have found later film cameras that had problems, and also a 1934 Kodak Retina that worked perfectly.......
Were these the old Pentax cameras with the threaded lens mount? By the mid '70s, they were already swap-meet cameras. In my teens, the swap meet was my camera shop. I'm pretty sure I had a Spotmatic, along with a Canon FTb, and others as well. Settled on a Konica system anchored by an Autoreflex-T. That was my yearbook kit in high school and then into college where I shot at the school newspaper. I never really cared for the Pentax screw mount. Took too much time and attention to change lenses.
In high school, I shot other people's cameras, all with bayonet mounts. I became a Pentax shooter in the early '80s with an MX and considered the M42 (then referred to as Pentax/universal screw mount) stuff as so much antiquated rubbish.
When this fine forum coaxed me into shooting adapted lenses on M4/3 and the denizens of PentaxForums spoke of the legend of Takumars, I got sucked in. Only recently have I fallen into the M42 camera rabbit hole, starting with the "original," the "AP." Shot the first film in 20 years, and have discovered the muscle memory of using a hand-held meter and "plugging in" the settings on the camera.

I've had NO luck finding any Pentax equipment of these vintages at thrift shops or pawn shops. Most local pawn shops have bailed on cameras altogether.
