Greetings, Gentlemen,
For colour comparison purposes, I scanned two of the S24 1877 5 ore and the 60 ore dark blue S31 If the 60 ore is dark blue, am I safe to assume the two 5 ore are S24 and S24a?
The 5 ore ultra piques my interest as it is missing one stroke
of the M of postfrim. Is that a constant error or an odd inking fluke?
Grateful for any help.
Michael
