Sorry for the poor pictures in the 2x2 but I am fairly certain this is the 1824/1 overdate. Can anyone confirm?
A very subtle part of the underlying "1" can be seen in the upper-left and upper-right portion of the "4". But there's more than 1 type. More:
If it's the overdate, the T-I relationship seems to confirm it as O-101. Left sides of the T-I should be in line. O-102 has the right sides in line, and the "4 over everything" has the I well right of the T.
