I didn't think any MF35 tractors existed before 1960.
I've got a part-tractor MF35 sitting in field. Early 152 Perkins diesel . . . sort of indirect injected and not DI like the newer ones.
It has power steering but I'm not sure what exactly you want and for exactly what tractor?? Not a "50s" model I don't think.
The parts MF35 diesel I have is serial # SNW 242331. Made in 1963 as I recall. Perkins engine # 1969589. Has Multi-power, power-steering, and live PTO.
