Origins of "rag-top"

Of course. As has been mentioned, many of the very first cars had buggy tops that folded down. What I was referring to was Eztrete’s post about the Chevrolet “turret top” replacing the canvas covered, wood-frame tops of the 1930’s.

The part of the top that appears “different”, here,here, and here, is a cloth, usually duck or canvas, covered, wood frame set into the metal of the top as in these 1934 Chevrolets.

And if you go to the home page of the url in the previous post you can see pictures of several convertable coupes, sedans, and a roadster with a rumble seat.

Actually, I did that before I posted here. Posted to the American Dialect Society Mailing list, with cc’s to OED and M-W. They monitor the site.
