Musketman: We used to have some information which gave the date equivalents for the letters and roman numberals marked in the rectangular box on Italian guns. It seems to be missing now.
Do you have any idea what happened to it?
As a general reference for others, it said roman numberal X = 1954. XI = 1955. The numberals continued up to XXVI which was for 1970.
They then used XX7, XX8, XX9 and XXX for 1971 thru 1974. They then went to a double letter method starting with:
AA=1975, AB='76, AC='77, AD='78, AE='79, AF='80, AH='81, AI='82, AL='83, AM='84, AN='85, AP='86, AS='87, AT='88, AU='89, AZ='90, BA='91, BB='92, BC='93, BD='94, BF='95, BH='96, BI='97, BL='98, BM='99, BN=2000, BP='01, BS='02, BT='03
I don't have any data about what they did after 2003 but if they followed suit BU would be 2004, BZ would be 2005 and CA would be 2006?
