Yes, it's a Linn C5 tractor half track built in Morris, New York and under restoration by John Belfield.
Here are some more pics.
John has taken on yet another amazing project. The vehicle had been "banked" meaning it had a brake failure and was run into a bank to save it resulting in the distortion of the cab and radiator. John is rebuilding it in it's current modified form fitted with a large winch on the back and dual steering.
It's Hercules engine is being rebuilt, having new valves made for it - also having one cylinder sleeved.
Can anyone provide any photographs of this rare and interesting vehicle in use?
PS Chris found it a little heavy to fit in his backpack.
