This is the Golde Top brochure describing the available factory installed and aftermarket types of sunroofs they install. Golde, a West German company, held several patents on sunroofs in the late fifties and the early sixties. Many European and American cars had them as original equipment as seen by the letter and the accompanying brochure.
