This is a large Indusrtial Thermograph by Fournier, Montreul Bois, France. An interseting piece of Industrial design from the 1950s and often referred to by our American cousins as 'Steampunk'. Not functioning, but would make a great restoration project or a lovely display piece. 430mm wide x 235mm high x 190mm deep.
