thanks!
I'm wondering if they had different optional trims like more modern cars, but more customizable...the radiator--blacked out, badges appear different in every picture Ive seen, rad filler cap is more olds-like than other pics. The one thing that seems like a definite Hupmobile giveaway is the curved cowling where it meets the windscreen.
Again thank you very much.. (the girl on the left is my MIL's mother, presumably at age 20)
