Well, I have finally come up with another one! It’s the practically mythical Curtis hard sided cab! It is in fantastic condition as you can see from the photographs, and comes complete with the cab itself, a windshield wiper, a flashing light on top, and a heater! Everything functions as it is supposed to as I tested it before it came off of the tractor it was mounted on.
It also comes with installation instructions and a wiring diagram.
With some modifications, this cab could also be made to fit on an RT5000 or an H5013.
