This is probably going to sound totally absurd but is it possible to either use the curtain mechanism from a Pentax K1000 to repair a Spotmatic? Either that or any other interchangeable components to convert a K1000 with no light meter and a Spotmatic with no curtain mechanism into a working Spotmatic (No I do NOT want a working K1000 out of this, I want a working Spotmatic). Any and all ideas (within reason) are welcomed...
