Among others I have this spoon.

With the following marks

which presumably means that it is made in Denmark in 1875 or at least something ending in 75.

Going though the databases on this site I believe that the presence of Simon Groth's mark suggests 1875.
The maker's initials appear to be ICFF which fits with I.C.F. Fordsmand - Roskilde 1893 - 1937 from the Danish Maker's Marks database.
So is the spoon from 1875 or from ICFF after 1893? It seems to me that the date should be right and there must be another ICFF.
and...... by the way, what is the spoon for? You would hate to eat soup with it.
