Back in 1963 a friend bought a red 1939 Ford Fordor. It smoked a lot and every now and then it would find a spark and a big puff of smoke would come from under the hood as a badly fouled plug found a good ground. The breather cap would blow off and smoke would come out of what I now understand to be the triangular vent in the pan right front. This happened once on the starting line at Milan Dragway and the starter and safety crew came over to see if it could continue. I waved them away and after 20 seconds I was crossing the finish at 60 mph for N stock eliminator. That 39 synchro floor shift was one sweet box and there was no clutch chatter. I wanted you to know that smarties in Hillman Imps could be put in their place. Later working for someone with a PhiBetaKappa key that owned a Hillman Minx I was able to edge out an engineer with a different Hillman Minx and the back window shot out. I have been browsing through the EarlyFordV8Club "The Flathead V-8 Engine Album" looking for the write up on steel pistons. After my first pass through of the 1932 history I formed the opinion in my mind that Henry Ford set out to update to fluid mechanics with a fuel pump, water pump, oil pump, and even vacuum windshield wipers, eventually in 1939 adding hydraulic brakes. Time passed and I decided to look up Model T, water pump and found the first almost 400 in 1908 had one. Then in 1917 ther was an oil pump assist for the dippers on the crank. It had a kind of rotating cone that might hint at the fluid drive for the fan on the 59 A-B. I saw it somewhere now where is "steel pistons?" My USB may have the answer in "Ford Times." Somebody complaining about neatness where I expected something on 1936 pistons. As the administrator said when I first posted. "Most of the people here don't want to dig that deep. They just want to drive their cars." If my question and leisure activities seem only fit for a blog please excuse me. What I found on HAMB Jalopy Journal says they were introduced in 1938 and not just an experiment. This message was edited by therunwaybehind on 9-26-19 @ 2:02 PM

The first reference to steel pistons that I could find was the Ford V-8 1937 Specifications that are included in the book 1932-1937 Ford V-8 Service Bulletins, page 410. The material is given as Light Weight Cast Alloy Steel, 301-305 grams. Previous specifications give the material as Aluminum Alloy, 287-291 grams. See also page 557 of the book 1938-1940 Complete Service Bulletins. Larry

I bought a copy of Ford V-8 Service Bulletins 1938-40 Complete including all 1932-37 revisions. It says on page 161. "In the 60 h.p. and Lincoln Zephyr only steel pistons have been used, both in standard and oversize." As well as a full page of other items from page 31 subject no. 6110. Thanks for steering me to this source for many things. I made it back to the specifications for pistons in the book I bought on page 557. It shows 333-337 grams for either steel or aluminum for the 85 hp cars 91A-6110A original steel and B steel service one kind with C & G service parts in aluminum.
