I have seen this before and have concluded it is not a factory 'special' but rather someone's marking of perhaps a Sherman or other auxiliary transmission system on their tractor. No documentation exists to verify this so I highly doubt it is OEM. Further proof is the hand stamping numbers and characters. FORD Hand Stamps used the capital letter "I" for the numeral #1, and the #6 was a lower case letter 'b' and the numeral #9 was an inverted lowercase letter 'b'. Additionally, look at the number '3' stamped on the housing and compare it to the number 3 used in the official FORD Hand Stamp kit. They are different fonts. Also, the 0 (zero) and 8's are questionable as well. So, that is how I see it. The 3 and the 6 are NOT the same for sure. The 1 is NOT an "I". You can't dispute the facts.
