The last Roaster made by coach builder Glaser-Heuer and the only one made of steel rather than aluminium. With Heuer build number K9/1, this Roadster featured an integrated windshield frame which accentuated the elegant body lines designed by Erwin Komenda.
K9/1 is considered “the bridge” in concept to the later 356 Speedster.
