Anyone who knows better please advise.
I was told D D marked Jerry cans were only made in 1957, 1958 and 1959. Prior to that I assumed Australia used British W D marked Jerry cans, and after 1959 Jerry cans that were unmarked except for the year mark.
I have also seen round petrol tins from the 1940's made in South Australia with D of D markings but not jerry cans.
