This realistic replica was built for the movie ‘War Horse’ and is now maintained in running condition to save wear and tear on the museums original WW1 tanks at events, including Tankfest.
The Tank Museum obtained the tank as it was used in Steven Spielberg’s World War One blockbuster Warhorse.
Though it looks like an authentic Mark IV tank, it was in fact constructed for the film.
Here is a video about the “tank” at the Tank Museum .
