Dodge D3/4 APT

[CanadianScottish]

I am looking for help in finding out some more information on and about the history of my Canadian Dodge T236 D3/4 APT. It was built in 1945 and it's serial number is 91168214. It was supplied on contract SM6423 Cat Ref 50, which I believe was a British WD order. Any ideas on who and or where it was supplied to?
It has featured on the forum before in October 2002 when a previous owner had it for sale on Milweb.
Any advice and or information would be great.
