About 10 years ago, I purchased from Randy Shuman of Newville PA, a very high condition Winchester Model 61 pump .22. It is chambered for .22 Long Rifle only so it has the higher optioned octagon barrel. The gun has serial number 10943 which makes it a 1934 production gun.
There was some crud in the checkered pattern of the steel butt plate so I removed it to make it easier to clean.
Inside the draw bolt access hole in the stock was a variety of stuff as pictured below.
And which turned out to be: 3 locks of very fine light brown hair wrapped inside some newspaper and a Series 1935A $1.00 Silver Certificate. I decoded some of the print in the newspaper, specifically, the programming for Thursday July 16th on station KOA. Turns out Thursday July 16 occurred in 1936 (my birth year), KOA was and still is a Denver Colorado radio station and the newspaper was the Denver Post.
Be pretty neat, but highly unlikely, if this triggers a search which results in finding the lad or lassie who originally owned this sweet Winchester .22 pump.
