Some thoughts:
American sets did have a range switch, but it was a slide switch, not a knob.
The term paper capacitor in American TV restorer parlance is easily misunderstood...We really should say paper dielectric capacitor but we usually contract it to paper cap out of laziness. If your set uses American sourced capacitors you need to be careful. Most makes in the US used at least some paper dielectric caps into the mid-'60s. Paper dielectric is not always contained in wax-paper outer shells...As far back as the 40's we took paper dielectric capacitors and encapsulated them in bakelite and other plastics. The plastic encapsulated paper caps (like Bumblebees, back beauties, Sangamo Tiny Chief, etc.) are as bad or worse than their wax-paper encapsulated brothers. Even some of the early orange drop style capacitors had paper or a plastic-paper dielectric (those rarely leak current, but are prone to go open or drift capacitance) sandwich.
Some other US sets before and after the predicta did not put a door on their HV cages, but instead to access the fly and HV rect tube required you to unscrew the cage from the main chassis and remove the cage as a unit.
