A Colt double rifle is less a mystery than the Parker double rifle. The Colt was a standard catalog item, although seldom ordered. Bruce, it would be very interesting to measure the bore diameters of the rifled barrels as well as the outside diameters. This would give us an idea of what your friend has here. Since the gun was in its present form at least fifty years ago, it is more than likely it came out of the Parker factory like that. We have another member who may be familiar with the early history of this gun, but I don't think he participates on this forum.

We did not measure OD when we looked at it because we did not have calipers. iD was nominal for the gauge and was one of the indicators we used to conclude that the barrels were as done by Parker. Frame size 1 1/2

I do not recall the exact ID as it did not seem to be significant.

There were several of these sold at Julias seven or eight years ago, I still have a 12 gauge damascus G grade that has a hammer forged damascus barrel with a 3?4 twist in the hexagon barrel.
I have never heard of any others, so I have kept mine.
A lummox at the storage dented the outside of the barrel so it is less than perfect, however these were don prior to the ribs being laid.

This is why it is puzzling when gun dealers and others who should know better make claims that only one was made. I am no expert on Parkers but I know better than to make such claims that can be quickly shown to be wrong through the make collecting organization.

Does the rifling on all of these rifled Parkers mentioned run the full length of the bore or only the forward 4 inches or so at the muzzle?

the parker rifled barrels are really interesting..if i owned one i guess i would be like craig and would want to know how it shoots at 50 yards and a hundred yards...i hope bill gets to measure one of these rifled barrels...charlie

What serve as sights on the 26" rifled barrels, of this 12ga. CH?

Never say never when it comes to Parker Guns, If it could be done and done without compromising the gun they would do it, I have seen many examples over the years, Gary
