King Tiger, no....tooo slow for an AA vehicle. Panther II, probably, but its turret ring would be too small also.. From what I have read on the Panther II, it was not designed to carry an 88mm. It was to carry the 75L100 gun. The Panther II would have been faster than the King Tiger but slower than the Panther because of the added weight from the armor they added to it. Supposedly the Panther II was larger, but by looks of the hull at the Patton Armor museum, by naked eye it don't seem like it. I haven't actually seen any of the specs on the hull any where, any one have those? Or detailed drawings maybe...hint...hint...Mark..?
