I will have the owner of this one try to find out if the Tiger from Kelly's Heroes is even still in existance. It's really only since the 80's that film production companies started either saving or selling their vehicles... before that, they were pretty much scrapped (or stripped down and rebuilt as something else). The exceptions being the vehicles that were "Hero cars" in big blockbuster films.
As I said, i do have more pictures, and i will post them later in the thread. The owner has quite a nice collection, including the M2/M2A1 in my Avatar, a German 105, a Japanese 37mm, and an M-24, just to name a few. The M2/M2A1 saw action on Guadalcanal, and has bullet pock-marks from Japanese direct fire on the grill slats. I have pictures of that vehicle too.
Oh, and the second job that I referred to in the OP is restoring these vehicles. So if you have something that you are modeling, and need reference, just ask, we may have worked on one.
