Canadian Humbers?

[mudeng]

I think the Humber armoured car and Fox are the subject of Canadian versions. Scout and Light Recce were all UK manufactured.
There is a difference in the MkIII and MkIV light recce, the MkIII had a large stowage box mounted on the rear, the MkIV had stowage bins mounted both sides, just forward of the rear mudguards. There were some changes to the vision slots on the hull front quarter panels.

I think I am correct in saying that the MkI was the "Ironsides" with open top, MkII rear wheel drive with louvred bonnet, stowage bin at rear and no vision slits on the front quarter panels.
The MKIII, rear stowage, vision slots on front quarter. 4 x 4 drive and I think fitted with runflats.
The MkIV, stowage bins on the sides, spare wheel carried on the rear plate, front quarter vision slots, and regular tyres.

There were other mechanical changes rear gear box ratios, but nothing that can be seen externally.
