For the past two to three years it has been gradually getting pretty darn sparse. Lots of double action autos and other black tupperware, but wheelguns, particularly vintage S&W and Colt's are scarce. The few I see regionally, Catskill and Adirondack areas, are generally over priced based upon their condition. I recently looked at a decent Victory, about 85% overall, non original plastic grips, missing lanyard ring. The guy wanted $650.00 for it. The other S&W in his showcase was a Model 10 no dash, rubber grips, about 90%+-, $500.00!
Even finding vintage shotguns, sporting rifles and miltary rifles seems to have dried up. I believe folks are hanging on to what they have because the economy is so volatile and/or, if they do opt to sell they expect to make a windfall profit. Judging from seeing the same guns, in the same shop showcases for years, I don't imagine anyone is selling many $500 Model 10's or $650 Victory models, at least not these days.
