Roadsters do not have roll up side windows... Convertables and Cabriolets do,,,, Roadsters do not have fixed
"A" Pillars,,,, they have windshield posts or stantions ?
Just my take on it,,,
I think officialu Fords last full year of production for Roadsters was 1936,,, 1937 shows a few made.. all laters where convertables or cabriolets....
