that my friend is not a Panzerkampfwagen VI "Tiger" Ausführung E, that is a Panzerkampfwagen V "Panther" ausführung F but very cool still
edit after looking some more, ive come to the conclusion that it is in fact a Panzerkampfwagen VII "Tiger" Ausführung B. Sonderkraftzeug 182 "Königstiger"/"King Tiger"
