Thanks St, John and I have talked concerning his possible, future decision to transfer the service into my hands. Have correspondence to prove it. From what I see, the barrel has vise marks on it and it may have been changed. If the poster could send photos of the barrel address, and close shots of the dates and inspectors marks, I can give a qualified opinion, but of course, John is the ultimate authority at this time.Someone else recommended sending the other Ainsworth to Dave Lanara.
Getting a letter from a known expert on these Martial SAA's is important
if one plans to sell them.
