From the 1921 film "The Nut"
I'm presuming it's a 1920 as cars in silent film were usually new cars? It has cowl lights (or at least it looks like it does) which should be a hint. Excluded already are Empire, Case, Elgin, Stephens, Dixie Flyer, National and of course Cadillac. It has some Studebaker similarities but I am sure it is not a Stude; the windscreen shape also doesn't match any of these marques. I searched many major and minor makes from 1915/16 to the early twenties, but I couldn't find a match. I think it might be a Paige? That's one make I had forgotten to look at.
I have two other urgent cases from the late 20s, but in accordance with the one thread per post rule I will send them in a few days.
