And very nice too. Perhaps a stupid question but why did she have a red funnel ?
Before the war, the Germans needed a method to distinguish specific vessels in the battle line. Since there might be two, three, four, or even five ships of the same class in the line, lack of a visual reference could become a problem during maneuvers. Thus the German Navy, like others, chose to paint horizontal stripes of either red or yellow on one or more funnels to distinguish individual ships, their squadron, and their place within the squadron. The designations (and number of stripes a ship may wear) changed as new ships were added and roles changed, but the use was continued during the war (more on that later).
