High condition or rare doubles are still in high demand. 12 ga field guns are just slow to sell. Perhaps the Cowboy shooters are no longer buying them up for their game. Demand for them is certainly very soft. Guns in fair to poor condition are very slow to sell. Shiny ones do sell even when they should not.
Names sell some guns beyond their real market. We've all seen Winchester, Browning, Parker guns in average or refinished condition bring serious money. I watched a Winchester Model 12 trap gun which had been refinished by a third grader but looked shiny, with too much Trueoil slathered on the stock, that was priced and sold like a 99% gun. Glad it's not mine, when the new owne learns what he bought he might regret his great find. Then again he only needs one buyer to take it off his hands so the pristine condition myth might outlive me.
