This type of roof was perhaps most popular in Germany in the 1930s, and is often called a "Webasto" since a German company of that name has been the main supplier for both factory built, and aftermarket, cloth car roofs since that time. This roof was used on many older cars such as the Mercedes-Benz Ponton, Saab 92, Citroën 2CV, Fiat 500, GAZ-M20 Pobeda and the Fuldamobil. Nash Rambler was available as a cabrio coach, but they called it "convertible landau".
