I found a series of photographs, showing the company car of Carl Lutz, a Swiss diplomat, who "served as the Swiss Vice-Consul in Budapest, Hungary, from 1942 until the end of World War II." [Wikipedia]. Images 1, 2, 5 and 6 show a mounted Notek-light. The car was equipped with trafficators (wigwags), painted radiator grill frame and diplomatic plate. All of the pics have been taken in and around the capital of Hungary during wartime. If the one or another sparks interest, ask me for high-resolution photographs.
