Yes, get out your 'FORD FARM TRACTORS' book by Randy Leffingwell as he mentions a blurb about the Ford trucks. Not ever mentioned is that the 9N four-spoke steering wheel was also used on those trucks only it had a horn installed. The center port had a shelf where it mounted. It was made by the same company and also had the chrome rounded center cap. The 4-cylinder L-head block design being half of a sliced down Ford/Mercury 95 hp/V8 auto engine already in production, is mentioned in Leffingwells' book and he is the most researched author on the subject. He says the 9N engine was 'devised essentially by slicing in half...", not that it was exactly that. "Adolph Eckert completed drawings, referred to as "9C", by mid December, 1938". "On December 28, 1938, foundry men cast the first engine, and the next day Laurence Sheldrick, Adolph Eckert, and Karl Schultz saw it". I have spoken with Randy on several occasions and he has done his homework, spending numerous days at the Henry Ford/Benson Ford Research Center in Dearborn, Michigan. He would have documented evidence to make this statement. The late, great Harold Brock has said the 9N Tractor was, and still is, a remarkable feat having been designed and put into production in only 6 months from the time engineering first began at the Rouge Building B in December, 1938, shortly after the handshake agreement was made. Vehicle design was usually done 5 years in advance and the design and drawings were all done on huge drafting boards with engineers in rolled-up white shirt sleeves, pocket protectors, and their sliderules. Parts were all designed, cast, tested, and repeated if part failed or modifications needed to made. Unlike today where everything is done on the tube, including 'simulation' for failure modes. Perhaps this is part of the problem today with so many recalls and bad parts/vehicles being produced.
