I've recently inherited my grandpa's Winchester model 1200 16-gauge and I'd like to find out a bit more about it. Specifically, I'm curious to know when it was manufactured. I've spent a bit of time with my friend Google trying to find a site that will get me the details, but I haven't found anything yet. I came across at least a couple of sites (oldguns and proofhouse to name a couple) that will lookup by serial numbers for Winchesters, but they don't include the Model 1200 in their lookups. Anybody out there have any ideas? Thanks much for any assistance.
