The Argus Golden Shield is a little bit of a mystery to Argus collectors. I don't exactly know too much about it, and the people that do know more about it know very little. According to another argus enthuisiast who has been collecting serial numbers, some of which have been Golden Shield's, the fourth digit of the serial number is supposed to indicate the year it was made, and the cameras were made in the late fifties, and early sixties. so a 9 would be '59 and a 1 would be '61.
