I will have to go back and look tonight. Thank you very much for the information. A lot of this I had found already but only in snippets and the way the link is laid out it helps tremendously. From what I can gather it is pre-1924 and proofed for smokeless. Given that it is pre-1924 then I would say that the "lettre annale" must be the squiggly 'b' that I can see making it 1923.

I have always had an affinity for doubles but never an opportunity to own any interesting ones. This came out of the personal collection of a closed gun shop. I happen to be left eye dominant and shoot left handed but when I shot this last weekend I hit 2/4 without trying hard. I don't have a lot into it so I am going to keep it around.

Would this have been commissioned for assembly or a production piece??

Thanks

Ryan
