Danish EF silversmith

[AG2012]

Hi
This set of marks is on Danish enamelled tea caddy spoon. EF within square brackets does not match any silversmith initials known to me.
Thanks for helping.

Haven't been able to find any similar pieces with the [EF] mark yet.

Do you have any images of the mark you can post?
