Pentax Spotmatics Anyomonous

Spotmatic F:Asahi PENTAX Spotmatic 'F' outfit I was GIVEN they other day !! Also there was a Weston Master III, Vivitar x2, tow sets extension tubes ( not Pentax),several small Vivitar flashes, filters etc -- outfit shown is: Spotmatic F Serial No.: 4647355,28mm f3.5 SMC Takumar, 50mm f1.4 SMC Takumar ( YES! -- the RADIO-ACTIVE one !! ), 150mm f4 SMC Takumar, Asahi Pentax Bellows... I have left the 'yellowed' radio-active 50mm on a window in sunlight all day and it has cleared a bit. The bellows foul the mirror of the camera body so I think it is not compatible with the 'F' model as it works OK on my older Spotmatic. The Old Gent had forgotten a FILM in side !! It was a 'Jessops 200' ( actually AGFA) so I cut it and processed and it was all very faint images, so Ioaded the rest into my older Spotmatic and downrated it to 100 ASA and on processing it was the SAME -- very faint images so the film had deteriorated so much -- but a 2005 outdated Kodak 'Ultra 400' rated at 200 ASA I tried all came out well and the 1/1000th second shutter speed seems accurate ! The other lenses were all fungus free and sharp !
