Need help identifying drum chipper

[Riseagaintreeservice]

I acquired this chipper from someone who passed, a power company owned it prior and painted it white(used to be yellow I think). Cannot find and tags, the only info I have is the engine is Ford I4 gas mid to late 60’s 172 or 192 cubic inch. The drum has 12” knives.
