Nothing to offer info-wise, but I just had to say it does my heart good to see one of my favorite (if only hypothetical!) vehicles getting so much attention lately.
I thought I was the only one digging the E!
I do have one unbuilt Panther II, but it's going right next to my E-100 and Maus in the "what if" section of my model shelf...one of these days.
Good hunting, Terry!
