Great article .......Thanks for posting it...
Does engine #10,000,000 still exist; if not, what was its final disposition??
Oddly enough it's reported to have been restamped in November 1926 among other milestone engines with new numbers, and probably sent off among the new cars(?) - and that's really odd since 1. it was an obsolete model that wouldn't fit with the floorboards in the '27:s that were built at the time and 2. It was used for a publicity run across the USA, so nothing that could pass as a new engine - maybe it was used internally in a company car?
From the encyclopedia:
NOV 18 1926: Engine production records, Ford Archives"Motor numbers ground off and replacement numbers: 10,000,000 to 14,548,000; 12,000,000 to 14,546,000; and 13,000,000 to 14,549,000."
