Some 40 years ago I bought an H&R M1 (1954 bbl date) from a knowledgeable collector/dealer who was local to me. Out of the muzzle of the bbl projected a paper tube about 2" long which I always presumed to be some kind of an oil 'wick'. I was curious the other day so retrieved the rifle and removed the wick which turned out to be about 24" long and appeared to be a rolled paper affair. I've never seen anything like it; have you??? Just curious.
