Thanks, Skeeterbd. I am still baffled as to the pedigree of my other 2" Twelve appearing on page 10 of this thread and who "J.W. Lewis" is. It bears "4016" on the trigger guard which is very close in number to Recoil Rob's Hellis "4135" and my Hellis "4105". There is no other serial numbering on any other metal work. It doesn't have the crossed staff date code engraving. It seems too much of a coincidence that all three guns above have four digit numbers on them with all starting with "4" with a range of 119 units. Gil
