Concerning ID.íng non Fords, I was looking a MTFCA Forum 2014 last night [ very learned guys on T's, but clunky format to use]], & someone put up a pic of an obvious non Ford Sedan. I could not identify it, but the majority of those Ford Model T guys thought it was a Model A!
I was amazed that guys who could pin down any Model T or pre T, did not know a later model Ford.
