 Dennis Carter demonstrated taking a tuning condenser apart on You Tube and then reassembing it, in his case it was from an Airline, likely made by U.S Radio and Television, of about the same era . To reassemble it he used shims that would fit between the rotor and stator plates, like still pieces of paper or plastic of the right thickness. It looked like what he did was put the rotor and stators in and the same time and then dummied in the stators by loosely tightening them down, but you would have to look at the videos again as I am writing from memory here.
