Laurent - Are you sure of that identification? "A.C." as it appears on an Italian-generated list, and the most complete list I have seen, is shown as an Unknown Inspector at Bologna in the 1890s. "C.A." is Afredo Cavalli and is much later, and found on both products of Bologna and Capua.
These initials are usually used with the last name (initial) given first, and then the first name (initial) give after it. So, for example, "C.A." is Cavalli, Alfredo. Some sources show the name as "Cavallo, Alfredo."
I wish the Italian Government would declassify this ancient information. The last word I had from out Italian friends is that this information is still coonsidered "secret" by the Italian Government. You would think they would declassify at least the names of the pre-1946 inspectors.
Similar to the name you gave, there was "A.A." which was Aldo, Adamo, at Capua. No dates given.
Just wondered what the source of your information was? The list I use appeared on the IAA Forum of January 16, 2007, posted by Vittorio, who seems to be quite expert on Italian Ammunition.
