I received this today. It is not about aviation but it is about WW2. I bought it for myself but I also hope that my wife will like it and we have a friend who knows a former WREN who served at the end of WW2.
It looks funny from this angle but it's correct. 1,2,3 are the blades of the rear prop. 4, 5, 6 are the blades of the front prop. #5 is actually in front of #3, not behind!
