Not heard of them either.

The Russian resistors were quite popular in in the U.K. in the late 60's & early 70's.
They were of fairly good quality & good stability compared to some of the easily obtainable U.K. types, but more to the point, were cheap. Looks like cost was a factor.
I still have a large development box of them!

The IC package is very interesting. Being ceramic, it could possibly been a MIL spec type. No markings anywhere I presume.
