I bought a Winchester model 61, that's the classical .22 hammerless pump, last summer. It's an early gun, probably 1933 or '34, with the extra cost octagon barrel and chambered for the .22 Long Rifle.
There was some mud in the checkered steel butt plate so I removed the butt plate for easier cleaning.
I looked up inside the hole in the stock that accesses the draw bolt and seen some newspaper stuck up there. After some effort I managed to get the newspaper out, mostly in small pieces but also found two locks of very fine light brown hair and a $1.00 Silver Certificate Series 1935A.
I was able to put enough pieces of the paper together and found it was from The Denver Post of July 1936. (Coupla months before I was born.)
Kinda neat!
