Quote from the SCSW IV: "Although examples are known in the AAA serial range, regular production begins at serial prefix AAD, with the lowest known early production in s/n range AAA0095 - AAA0789."
So, not "pre-production" and not "regular production" - by the standards listed it would be an "early production" gun. Not sure if that enhances the value or not. Interesting for sure. Has it had the recall done? Again, don't know if having it done would hurt, help or have no effect on value.
Adios,
