Hi,
There are 3 assayers in PL with initials ИК
No 3777 I.Krapavin in Kharkov 1849-1850
No 3132 unknown assayer in Novocherkassk around 1856
No 2114 unknown assayer in Moscow 1872-1881
The first two are too early and rather rare.
The Moscow assayer is the best candidate matching your mark.
The first letter in maker`s mark cannot be seen, could be A, Л or whatever. The second letter is either H (N)or K.
That`s all I can tell.
Regards
