I found this picture of a model , and I would like some more information on this vehicle. Was one (or more) actually built? If so, where can I find more information? And more pictures? And line drawings?
I've been searching for days now, but I can only find more pictures of the model, not of the truck. I've checked online, and I've gone through quite a few books. Can anyone help me with this?
Thank You.

I think what you have there is a model of an AT-45 heavy artillery tractor.

Thanks Keith! That's what I'm looking for.
