Actually there are about 7 Panthers in running order. I believe this is Ausf. G from Kubinka museum. On the other hand, there is only one Tiger tank left running (7 preserved in total and one excellent Russian replica) in Bovington Tank Museum and one King Tiger (9 surviving in total) in Saumur, France.
I'm glad to hear about the Panthers though i kind of disappointed about the Tigers (especially the Tiger I), Though i saw the Russian reproduction Tiger I in youtube and i was impress.They even went as far to copy the overlapping suspension on that tank.^^
