Here’s one of the Kings of shotguns: A 12g Boss Sidelock Over-Under. It’s in fantastic original condition, and it’s coming up at Julia’s March 2015 sale.
The Boss O/U was created in 1909, and the innovations it introduced are still in use today. If you shoot a stacked-barelled Beretta, Perazzi, or Fabbri, your gun descended from the Boss O/U.
The Boss O/U has always been an especially difficult shotguns to make, and a single gun like this with two sets of barrels and a single forend would have been even harder to build. Only the best of the best workmen at the company would have worked on it. The gun would have been incredibly expensive to buy, too. Having a new one like it made today would probably cost you close to $200,000.
