Interesting story. They also have a mock-up built near Stirling Castle and it looks different then the Nova built Trebuchet and the American made model mock-up. Learned about WarWolf in the BBC series below. Very good series. There are 5 episodes each with 6 parts. Would like to see additional episodes if they have been made.
