I would like to you to help identify the maker (and assay master) of this silver basket.

Unfortunately the marks (and the punch of the maker) is worn.
It is obvious for me, that the item is from Moscow, fineness 84 zolotnik.
I found 2 possibilities for the assay master but I'm not sure about the reading. it is N.K or И.K.

The first 2 characters of the year it is 18 and the last one is 4.
The mark of the maker is worst if it is possible.
Surely i tried from every side, but I can't read.

I can't read the marks. from some angle seems to me K, but if I see upside down I see Я
I see now, some of the pictures little bit out of focus, and some of them glinted a little so. if it is necessary I can make more.
Please, try to identify.
Thank you for your help!
Best regards!
