Sometimes you can find interesting papers inside frames! A good builder will have soaked the stuffing with liberal amounts of oil or grease.
I will add that I make one exception to the above rule. If the seatpost is hollow and you can see down it, I ram a cork up in there. Not the seat tube, the seat post. I can't fathom why more builders didn't do this back in the day. As far as I know, I'm the only one who does it and I can't see a downside.
