It doesn't have a vehicle identification number because it's not a vehicle. The serial number isn't traceable (or not easily traceable) to anyone that bought it as surplus.
I saw the first C&C video about it and was intrigued, so I did some more research. The engine design is very, very industrial and doesn't have a lot of performance potential. The cylinder head design is similar to a 1950s Buick nailhead V8. Personally, I think they sound worse than a Volkswagen flat-four and are even less desirable.
