Chevrolet CGT in British or Canadian Service

[kosbie]

Hi guys
My Chevrolet CGT is progressing. As my 25pr and limber are British I am as yet undecided as to whether to finish it as a Canadian or British Army vehicle. My question is this - does anyone know which British Army Field Regiments used the Chevy gun tractor in WW2? Did Canadian Field regiments sometimes have British made guns and limbers?
(As yet I know nothing of the vehicle's actual history)
thanks
