After the husband of my wife's college roommate died, I helped the widow dispose of around 30 firearms, and she insisted I keep one for my troubles, which I did (a Ruger Blackhawk Bisley style revolver). We knew that couple for the better part of a half century, and as long as the widow is alive, I won't sell the pistol, even though I have no use for it. When my Dad left his farm, I helped him sell about the same number of firearms, and in the course of those projects I developed a strong desire to spare my son that particular chore after I'm gone, so I got rid of a fair number of my own long unused firearms. I got a little too carried away, and now, past the age of 70, I find myself in the market for a thing or two. It's weird, but actually kind of cool. My buddies are trying to justify, I dunno, a 28 ga. sub 6 lb SxS, or buying a curio and relic from Holt's, or whatever, and I'm off looking for a garden variety, all around 12 ga. o/u game gun that eats steel shot and weighs 7+ lbs so I can get back into sporting clays (or duck hunting, or late season pheasants, or something, let's face it--it's just an excuse).
Oh, my son likes guns well enough, but our tastes and needs are different enough that I'm sure he'll keep a couple of things for himself or my grandson, and get decent value for the rest. I'm okay with that. In our family we get all sentimental about dogs, not guns.
