Lol, two years from now the way things are going I may be locked in a small room and given finger paints and Mister Potato Head to play with instead of sharp things like X-Acto knives...
I'm in for the Armour in the West GB for sure- I've got a Tasca/Asuka Model M4A3E2 'Jumbo' Sherman I think should fit pretty well and I'd love to build.
As for you SP I'm not sure about Vietnam but I picked up a Dragon Super Sherman Isherman for twenty bucks that should work for an Israeli/Arabic GB.
Has a 'What If' build been done here? I know a 'WTF' GB idea was tossed around but never got started. I think it would be a pretty cool idea and would get a great deal of interest. Found this site on Japanese X-Plane research a while back, I know German subjects are more popular and actually have kits of them but there is some truly wacky and wonderful stuff here.
