Question about coupes

Bill. Yes all 1935 /1936 cars were set up with roll down rear windows in coupes . Were 1931 / 1933 were only roll down with rumble seats. Randy

RE: 31-33 coupes, I have been told that unless the rear window rolls down the car was not originally equipped with a rumble seat. For many years I had an 851 coupe, dual ratio, sidemounts, etc. The rear window rolled down, but the car did NOT have a rumble seat. Is this normal, or did the factory just happen to make this particular car in this configuration?
