What month of what year was the Icom Pro III was discontinued ? I have what I believe was one of the last batch runs of that radio. Was bought New in April of 2010 and the serial is later than any of the recent radios listed 3206720
To the best of my knowledge, Icom has never explained the format of their serial numbers. At least, they don't make sense to me, and never have. In any case, I suspect yours is a late run, but that's not a given.
