Notes
Knob for the push-pull ignition switch on Farmall letter-series tractors, the Cub, the McCormick-Deering W and O series and the 200 to 450. Burch Store lists its replacement as 8732D, marked OUT - RUN / IN - STOP, and showed it on back order when checked. This is the knob only, not the switch. The lettering needs care, because flat text ceilings are a known cause of Slant 3D print-check failures, so the text design should be tested early.
