173 FG

Folkard states:

State 1:- East side weak near top; letters normal.

State 2:- not recorded.

I would think that Steve's example below is a later state 1, re-entry would have normally strengthened the East side of the stamp. It does show a degree of wear in the East network and the adjacent background pattern.

Imprimatur
