1942 Australian 12 cwt Chevrolet Ute - Help!

[David_Hayward (RIP)]

I would have expected a Letter for the month, i.e. A = January, to L = December including I = September, followed by digits for the day, i.e. 1 - 31, and then say "4" for 1944 or "5" for 1945. E.g. on Engine # WR 3808775, Casting # 839253 there is a date code: C52 for March 5th 1942. It is possible that as it was wartime still the castign foundry, McKinnons Industries Ltd of St Catherines, Ontario, used "10 4" for "October 1944" and no date code.
