My guess would be a WW2 Diamond T, or possibly an early 50s Kenworth/Peterbilt.

Thanks for posting that, I haven't been able to find pictures of that before. It's a lot different then I remembered.

Another thing I was looking for, the site has pictures of the villain's car from Oliver & Company as well.

My guess would be a WWII Military Dodge truck

Slightly odd request - anyone who has seen this Disney film may remember that the main bad guy drives around in a huge half track which look like it's been made from several different vehicles.
What I'm looking for is suggestion for the likely source of the truck cab
