Interesting brochure. To me it looks like the Colt badge under the Mitsubishi logo on the grille is not the same as the actual early UK Shoguns (IIRC that was the same font as the COLT in the image they have used on the number plate. In fact the badge seen here looks to be that used on the American Dodge/Plymouth Colt cars.
I think they have just stuck the COLT badge on for photographing for the brochure. You can see it is not present on the white vehicle, only the blue one. They probably didnt have any badges to hand that were in the font of the Colt Car Company, so they just stuck one on that's in the font of the Mitsubishi Colt car (as opposed to the Colt Car Company, if you get what I mean).
