Today I visited a farm and its new owners. I found a spent shotgun shell that appears to have been there quite some time. Red plastic, "W-W" headstamp, 12 gauge, 2 3/4 inch, printed with "Winchester Western 6 Duck & Pheasant Load." I'm trying to come up with even a ballpark of how old it might be. I assure you I know less than nothing about guns or hunting, but I *do* know how to use the internet, and it appears that anything that used to be called "Winchester-Western" now is just called "Winchester." They have no products on their website with this name or anything close. I've seen collectible/vintage boxes of what appears to be this exact product for sale on eBay where the packaging looks kind of fifties-ish, but I can find no mention of a year on any of these sales. Can anyone narrow down the timeframe on this thing for me at all? Even if just to say "Winchester stopped using the Western name in 19XX" is better than the nothing I got now. Thanks!
