Hi Miles,
Look what is suddenly crawling in, a Bigorne? French Ordinance of 1st July 1818, a system of countermarks on the opposite side of the guarantee mark. These countermarks are known as "bigornes". I like to know which French guarantee mark is opposite the bigorne? Agewise, my guess is as good as yours but I keep it around the turn of the 19th century perhaps you should try the French section.
Best,
Oel
