With respect, notice to the dealers of that change in the font for 1, 6, and 9 took place in the February, 1931 Service Bulletin, more than a year before the production of the first V8. I do not know if an additional change took place in 1938 or later, but its highly unlikely that Ford reverted to the pre-'31 font that shows on the subject transmission.
