It would depend on how much is 1912:
The serial number on the block
Low head would not say "MADE IN USA"
Hogs head is aluminum with Ford script inspection door
Intake is aluminum, with correct carb
Timing cover would probably have oil fill combined with timer
Tea cup oil pan with correct door
Eventually, I would like to find a late 12 motor for my late 12 touring, however as of now, all I have are parts for trade.
