Congratulations from me too, Patrick
And, of course, Pal and everyone else that tried to solve this one.
I will say on my behalf, I did try too and spent many hours on alternative Norwegian sources but came up with nothing.
No points, but maybe I get a pat on the back for figuring out it was not on a named car chassis but a Commer vehicle that was possibly a rebadged Hillman.
Nice puzzle, Galrot.
