Hello Messman,
I thank you for your kind remarks. You are most welcome to utilize any and all of the units I have posted to either include as is, modified or completely rebuilt as you wish. As I have stated before, anything I have made and posted are to be unencumbered without any restrictions as to their use or abuse

Skin them, modify them or use them any manner you see fit to do.
I am not quite sure I understand in your posting if you are wanting some different masks for these units (or others). As a matter of preference, I do not mask the gun barrels preferring them to be the same skin/camouflage color as the tank unit. This also leaves one the ability to make a mask that will employ different colored road wheels, sprockets, etc. I did mask these shadows in this set with black.
The reason I made a multiple choice selection of any particular type of given unit is so that anyone who wishes to include different versions of say a Panther, Panther II, E10, E75, E100; will have the option to employ more than one version in a game scenario. This will allow recognition/identification of specific units in game play not only with camouflage/skins, but also with details on the unit. Thus one could theoretically have four different StuG III's, several Panzer IVJ's, (some with skirts some with partial, some without, etc).
You can Private email me on the forum and I will be happy to assist you in any manner in my limited range of skills.

Old Timer Panzer General fan. Maybe a Volksturm soldier now. Did they let Volksturm drive Panzers?
