Ron;
Actually you can restuff those style of capacitor, SOMETIMES, like the Sangamo "Little Chiefs" or the bumblebee types, with a molded plastic shell. I'm not sure whether you can with those blue Cornell-Dubilier ones, but since they are replacements not original to the radio there isn't much point. The odd thing is that I have run across some of those plastic molded capacitors that still test good, so maybe the later ones used plastic film, or a combination of plastic film and paper, that holds up better then the pink and blue Sangamo ones. If anyone wants to find out how look up a You Tube channel by a guy named Dennis Carter, it's rather interesting, but it only makes sense to do with radios, and TVs, and in his case a Webcor wire recorder, that left the factory with such caps.
One thing that I have been looking for are sources of smaller diameter cardboard tubing in order to make replica capacitor shells. So far the smallest that I have found are maybe 5/8'' inner diameter tubes from a Saran wrap or wap paper rolls. I have heard that one source of smaller tubes are those wire hangers that the dry cleaners use but I haven't found any of those yet. I was looking at tubing for fireworks but they seem to be thicker walled then capacitor shells.

Arran
