Jim Kelly's background has been discussed previously but the OP may not be aware of his credentials. When Jim was in the USAF over 50 years ago, he was an armorer. He was stationed in France and he became General Curtis "Bombs Away" LeMay's personal gunsmith. While in France, Jim was allowed by LeMay to apprentice in French gunsmith shops where he refined his craft. Mr. Kelly did the stock replacement for Bo Whoop, Nash Buckingham's legendary Super Fox duck gun which he had lost decades before.
