I am German and I am still wondered why this Tank become so famous... I mean it couldn´t change the war... The Panther was technical better because of its weight it was more reliable... but more famous and respected is the Tiger^^
Tiger 131 was a rare prize for the Allies, IRC, it took a penetrating hit that scared the crap out of the crew and caused them to abandon the tank, Allied forces promptly closed in and captured it intact; the hit had only damaged the hull, so 131 was promptly shipped to Britain and run through numerous tests to see just what this new terror weapon could really do; because of this, very little restoration was ever needed.
One from Kubinka Tank museum in Russia is also running. Only it was last turned on about 30 years ago I'm not certain if the one from Musée des Blindés is "operational" but it is also in very good condition.
