Here’s a good example of a model 90 Empire Tractor.

“Empire tractor built in Philadelphia PA using Jeep componthrents from radiator to rear end including the entire drivetrain. This unit has many original parts including hoses, hose clamps, wiring and wire clamps. Engine and drivetrain are all original. Tool box is a reproduction. The light switch has been changed and possibly the temperature gauge. It’s a three speed with a two speed transfer case. Road speed is 25mph plus. Reason for selling : I’m older than the tractor and loading/unloading at shows has become a chore.”
