I have already contacted H&H and they say the records do not show the gun as a Paradox, I have also bought the book on Paradox by David J. Baker and Roger E. Lake and read "that the H&H records are not complete. There are all degrees of missing information, up to and including all the details on a number of Paradox."
I have contacted Roger Lake and he said that the gun based on my observations (as I did not have the gun in my possession) that it may have been built by W.C. Scott for Holland and Holland. This gun is clearly a Paradox, there are the markings H2227 on the frame and the barrels, the barrels serial number is 15103 of which H&H had no records. It is believed that the serial number was a mistake by the person stamping the barrels.
Any additional information would be appreciated,
Ken
