The Do 27 was the first mas-produced German aircraft after WW2. It's a very effective STOL design that found favor with several armed forces. It was not so popular on the civil front, largely as the purchase price was twice that of an equivalent Cessna. Nevertheless, it was an advanced design and over 450 were built. This one was on show at Germany's Deutsches Museum, Munich, in 2022. There are now several kits of the aircraft available, so these pics should come in handy.
