With all the Boomers moving on...
Trends and markets will be interesting. I predict a Glut of barely used Harley's and Hot Rods getting cheaper.
Looking at shotguns I see a huge influx of well used European field guns being imported. These are old 1940-50's club or game guns that travelers might have used wile on a trip. I'm not sure what is going on, old estates or clubs folding up. Someone, somewhere, is buying up all these old double barrels and importing them. Most are simple made with double triggers and extractors. Some cool old guns at fair prices. Not many younger guys will be wanting them. No steel shot through them, it will break soldered ribs loose. No magnum loads either. But still fine old game guns. Some old guns didn't even have buttplates, they simply sanded and checkered the flat wood ends.
This is just an example of the type. This old boy imports stuff that is usually rode hard and put up wet. But it's interesting, wonder where he's getting them. A quality and type we won't likely see again. There are some nice Spanish, Italian, and English examples coming on the market.
