I did find this on a discussion board over there

"There are a lot of tractors with low production numbers that only have
1 or 2 examples known to exist. The ILLINOIS tractor built by the
Bloomington Silo Co., Only 2 known to exist."

I have an owner's manual and parts list for an Illinois brand tractor.
The copyright date is 1919. They were made in Bloomington, Illinois.

Anybody ever hear of one? Recommendations for more info? I would think
a mint manual with the warranty registration card still inside would
be more scarce than a tractor. If there is a tractor out there, I've
got your manual.
