Quality will always have a market. But average condition, used box locks just seem to have little market these days. It comes down to who is buying and what they want. It is O/U there and O/U or semi autos here. I suspect it is the same thing here on handguns, wheel guns or out of fashion while semi autos are the rage with young shooters.

Markets change, needs change, taste change, what does not change is the seller wants more and the buyer want to pay less. Anyone who bought guns as an investments has seen most of his profits go up in smoke.
