Hi Pieter, welcome to this forum! Glad to see another Dutchman here.
I don't have any info re. 8th Recce. You mention armament on jeeps - I have to still see the first picture of a Canadian Jeep with machine-guns or the like.
As a start, see
Armoured Acorn > Canadian Vehicle Markings, Parts 9 for detailed info on how Canadian Jeeps were marked.
Did you try contacting
the 8 Recce Association?
M.vr.groet,
Hanno
