Agree with Mike, the paper caps do not look as if they have ever been restuffed.

Lots of older Philco paper caps used some sort of hard substance on the ends. It is very difficult to unpot these, but not impossible. Heat will soften the end cap material...but caution must be used so as not to overcook the cap and scorch it (been there, done that, have scorched caps to show for it).
