Kirk, congratulations on your new Allis purchase. The 20-35 is one variation of the Model E tractor (aka Model "E 20-35"). The last version was the E 25-40, the predecessor to the Model A. Your 20-35 appears to be very straight. One expert on the E and A tractors is Norm Meinert (815-865-5372). He can supply you with engine parts (if needed) and valuable expertise. Another good parts source is Larry Swenson (507-787-2338). Best of luck with your restoration.
