One more thing on the subject of re-stuffing paper capacitor shells, don't assume that just because the brands and or labels of the capacitors you find under a chassis don't all match each other means that they are not all original parts. The big guys like Philco and Brand Z may have installed caps with their own branding on them but many of the small and medium sized manufacturers did that. For example in one post war Electrohome radio I have worked on the caps did not match, there was a mix of Aerovox and Solar Sealtite caps under the chassis, the only cap that was changed, in one of them, was changed by me 20+ years ago, and it was a Sangamo little chief I stuck in there because I didn't have anything else. I don't doubt that this was true of many other manufacturers, they probably needed some .05 uf at 630 vdc and found that Solar could furnish a reliable supply but Aerovox could not, however Aerovox could come up with all of the .005 ufs and .01 ufs they wanted, or maybe Solar offered a better deal? I see to have also remembered running into both Sprague and Cornell Dubilier paper caps in a Rogers I was working on, there were some replacements but those were mostly 1940s vintage so they got re-stuffed and put back in since they didn't look odd, yellow plastic do, so do orange drops and disk caps in a vintage radio. About the only detail I fuss about is getting a cardboard shell with the same capacity and voltage ratings as the O.E.M cap is it has been replaced, they all get 630 vdc yellow caps stuffed inside regardless.
