For those with "The 1932 Ford Book", you will have read that according to the Dearborn Engine Plant log, the engine at the Henry Ford shown in #1 and #2 above is #1 only in the sense of it being the first considering worthy to be installed in a vehicle for sale (Job #1, in this case, a Victoria, on March 10, 1932 in a ceremony at the Rouge Assembly Plant where Henry Ford stamped the I8-I on the transmission bell housing. The first three of the attached photos are of that ceremony on March 10th. Note in the second photo the overhead body drop fixture is still in place.
There were three V8 engines transferred from the engine plant on March 7th, #242, #243, and #244. According to engine plant log, #243 was selected to be 18-1.
The last photo shows what is perhaps one of the first 241 engines that did not make the grade. One can only wonder what the thinking was behind locating the starter motor on top of the bell housing.
How it ended up in the hands of the Henry Ford isn't clear, although a good bet is that it was removed from the Victoria chassis along with the other first 1,928 initial engines for major revisions and another engine and transmission took its place.
That shown in Sheldon's photo was neglected for many years until Lynn Stringer (RIP), former Director of the Early Ford Club, received permission to clean it up and restore some parts of it that had gone missing over time. I had the privilege of supplying some of those parts.
