St Petersburg maker MK 1858

[carlislepaul]

Gentlemen

I read the marks as St Petersburg, 84 fineness, Assayer Eduard Fyodorovich Brandenberg, 1858.

Can anybody please identify the maker, the initials appear to me as MK, but I stand to be corrected.

The maker's initials seems to be MK and that is a to name unknown master 1837-1869 or at least its looks very much like his mark. He is know to have made spoons.
Mind my saying but the assayer's last name is BrandenBURG not ...berg. He worked 1850-66 in StP.
