I do not believe that the Ordnance Mark increases the value except for a mint condition to a limited niche of collectors.

I disagree that the extra barrels do not add value. They will add value if they properly fit and give the gun more versatility (say 30 inch barrels and a second set of 28 or 26 inch barrels and they have different chokings) How much value do they add, a couple of hundred.
