Concerning the cutout purpose, I am sure you got it, the reason is obvious. It could be found on many British trucks (pardon me, lorries). I would be interested if it is possible to identify the truck type according to the L-number. My being a scale model enthusiast, I would consider it interesting theme for some future modelling project, but even if it is GMC CCKW, there are still variants, 353 or 352, canvas or sheet metal cab, w/ winch or w/o winch, w/ gun mount or w/o gun mount etc. I would appreciate any thought, ideas or comments.
Happy searching, Jan.
