For the 1940 Olympic Games in Helsinki, A&R built the Germania IV for Krupp in 1939 under construction number 3340 and sail number 8G12 and the Windsbraut III with construction number 3338 and sail number 8G11. The client was the private banker Fritz Sponholz from Berlin Charlottenburg, who had already successfully sailed the 75 square metre national cruisers Windsbraut I and II, both also built by A&R. Sponholz won several regattas with the Windsbraut III in the 1939 season, including the Finland Week on the Olympic courses in Helsinki, as can be read in reports in Yacht magazine.
Unfortunately, the Second World War cancelled all Olympic plans and the Games in Helsinki did not take place until 1952, albeit without the participation of the 8mR yachts. It is not known whether Fritz Sponholz survived the war as unscathed as the Windsbraut. However, he appears once again in the A&R construction number book in 1945 with an order for an Olympic dinghy. Otherwise, little is known about him. The only documented record is his voyage from Liverpool to New York in 1908 at the age of 25 on the luxury steamer Mauretania of the Cunard Line.
