Not Chalmers-Detroit....I'm not sure if the second name could be the name of a town, anyway not one of the most well known.
Thank you, it rules out a lot of names!
Not Allen-Kingston, Coates-Goshen, Detroit-Dearborn, Firestone-Columbus, Pope-Hartford, Pope-Toledo, Pratt-Elkhart, Stoddart-Dayton and few more, then.
Great-Smith?
