Keith,
There will likely be a market for higher grade small bore gun for some time to come. But, make no mistake, the market for standard doubles in 12 gauge is already beginning to erode. As is the market for John Deere two cylinders, Ford model As, hit and miss engines, wringer washing machines, Belgian A5s, and other stuff from a bygone era.
I doubt the talent exists to produce a mid 1960s vintage Japanese 35mm film camera anymore. But, that doesn't mean values are going up on the existing ones any time soon.


Best,
Ted
