Interesting picture. OWI does indeed sounds like "Office of War Information", but I have no idea what they actually did (apart from what I just read on wiki
) and why they were in UK/Canadian territory.
The vehicle has to be a Chevrolet. The low stance made me think it could be a small pickup, but the cut fenders and big wheels suggest something bigger....maybe a 1,5ton truck??? Is that a seam above the windshield?
