This is a nice start of a version of the vampire that is not so popular. However, the trainers were numerous with many air forces around the world especially in areas of British influence.
I had the opportunity of seeing a British version in France when I was working with Airbus. They had an aviation museum in Toulouse.
I know that the French built many single seat Vampires under license and named them Mistral.
