I think I've seen that one.
Its about Polish pilots that fled to England and formed their own air wing to help fight the Nazi's in the air.
There are only about 50 airworthy models still flying, most in the UK at Duxford Air Museum. Then the US has about 10, Australia 2.
Many more are undergoing restoration. Even though they are over 70 years old, they still look and sound magnificent. The one photographed above is stored at the Duxford Air Museum, but I photographed it at the Shuttleworth Exhibition.
