IMHO yours is a repro, the porcelaining isn't consistent with correct early 1900s.
Should be thicker porcelain process, and as pointed out the face is far too "clean" vs edge damage.
If you look at the cross line in the F on most vintage Fords they tend to be thick and/or extend to or nearly at the bottom left-curl of the F-base. .
The complete font tends to have ends with points rather than blunt flats.
The 1912 bird logo you have should extend further and given the other known good piece it is not the same.
