looking for Anklam (Germany) hallmarks

[Theoderich]

I am looking for old Anklam hallmarks.


I got a makers-list, compiled by Father Becker, includes more makers than the book by W.Scheffler.
But I do not find the maker of this spoon.

there is an incription from 1835 or 1855.
The makersmark looks like [JFK] but I am not sure.
Can anybody help? Have anybody other marks of Anklam?
