I have a Winchester Model 12 Heavy Duck 3 inch chamber shotgun. It has a solid rib 30 inch full choke barrel. It has been completely refinished. All of the metal has been covered with Dura Coat. The stock has some minor crack repairs and has been refinished. The serial number indicates it was manufactured in 1956. It appears to function perfectly. I realize that the refinishing decreases the collector value; but I wonder what it would be worth as a shooter. And is it still a desirable firearm?
