Found Inside 1953 René Herse Frame……

I started work today on a 1953 René Herse Randonneuse. When I removed the fork I found that the ends of the top tube and the down tube were plugged with screwed up pieces of paper. The top one was a sheet of lined paper with some indiscernible faded writing on it and the other was a flyer for Stronglight, stating their victories in competition during 1952, including the Bordeaux-Paris. I wondered why Herse would have plugged the tubes like this and the only thing I can think of is that they might prevent contamination of the Herse dynamo contact brush located in the head tube, if the bike was turned upside down. Question is… should I put it back?!
