Dodge D60 - or not?

[jsim]

Hello,
I'm trying to identify the truck (lorry) in the attached photo. For quite a while I thought it was a D15, but now think it may be a D60, could some kind soul help please?

My reason for asking is that I believe that between 1943 and 1945 my father drove this truck the length of Italy and France, where his RAOC unit joined 21st Army Group in support of the Canadian Army and continued through the Low Countries to the Dutch/German border at Enschede.

Thanks,
John
