I bought the "C" and am going to make it after a few other projects get done. I plan on putting an interior and 'fence' on front, which is used to defeat shaped charges. I have some photographing and measuring to do before I get into the project though. The kit looks good from just taking a glance at it in the box.
I'm always amazed at how BIG an S tank really is. In the photos it looks like a sports car, but in real life... WOW.
Patton Museum has one operational.
