This was the tractor based on the M41 Walker Bulldog tank chassis that was used to tow the Skysweeper AA cannon back in the 1950s. Most served in Germany or Japan in the post-WWII theatre of ops. Very few survive, and my efforts to find any information on them has since been fruitless, except for what I have listed above, and one or two pics from the Internet. Looking for more info on the tractor, especially pictures. Any help is appreciated.
Here's a sample pic of the tractor to show what it basically looked like:
