The marks are as follows:
1 then
(looks like cursive) ZiD inside an oval then
k followed by Hammer & Sickle inside a star followed by 875.
I know Hammer & Sickle denote Soviet and the 875 is the purity.
I am uncertain of the 1 with ZiD or the k before the Hammer & Sickle.
Any information would be greatly appreciated!
