I can state one BIG reason with some pretty convincing authority after selling my last 20 Contenders and all their realted gear the last 3 plus years via the classifieds on several forums. With the economy (or trolls using it as an excuse), not that many buyers are looking for complete Contender UNLESS they can buy them for pocket change. With my 20 frames, only one was sold with its custom barrel and custom furniture and all the rest were sold as frames alone. The one (minus the scope) because it was a one of a kind and well known, and for less than it could have sold it on a gun action (I chose not to use them). That meant I had to piecemeal off a truckload of barrels, furniture, scopes, mounts, parts, tools, most of the reloading suplies and dies, etc for them sold one at a time. I set fair to lower than fair prices on most, giveaway on some and literally gave some away to finally get them all gone, and it took that long.
And to add to the mix, it's taken me about 7 years to sell around 45 other firearms as well for fair to lower than fair prices, many still new in the box for less than I paid for them years ago. I still have a ton to sell, but after that many years trying I tend to put it off rather than dealing with all the trolls. FWIW
