The maus done by DP if i remember correctly, and E-100 im not sure.
Yes, E-100 has already been finished, stumbled across this a few months ago.
EDIT: This was the link where i found it. http://forum.worldoftanks.eu/index.php? ... -drawings/
Note: Only the E-100 and JPE-50 pictures work, the Panther2/E-50 and Porsche Tiger II don't.
