.22 ID help please

I got the 5 together described as Russian… These are steel cases (magnetic) The single has a K stamp.

Any info welcome please.

Starting from the second Soviet Union,
how a pack could be seen here, your cartridges were equipped in the years 1930-1960

And this is the cheapest version of equipment.

The raised “K” in an impressed dish is by Kynoch

Thanks Pete, I suspected it was Kynock.
