Bob, I didn't compare the article with the book chapter paragraph by paragraph, but the book was published two years after the article, so I assume the book has more and later information. By the way, I have a wonderful little 28 gauge Arrizabalaga that is assumed to be a Model 116, made in 1961. It is brand new, unengraved, case colored, fitted like a Purdey, wood to metal as good as I have ever seen. I don't know who the importer was, but he should have kept it up. What a great little gun. William Larkin Moore sold one exactly like mine a few years ago for $5000, after it was on his website for a very short time. I called him about it, but it was gone. Moore's gun and my gun were identical and would have made a great pair. Of course, yours it in a different universe. Congratulations.
