The action looks like a Francotte based on the H&H. They are very fine guns and in good shape run in the $6-7K range. The tubes are Whitworth with the proper Whitworth serial numbers & trademark on them. The practice of numbering the Whitworth barrels was similar to (maybe the same as) many of the British patents where the gun had a serial number and another number was affixed to show how many times a particular patent (A&D action for instance) was used under license. I guess it was a way to keep track of royaly monies for use of the patent.
Great gun!
