It has been said at many places on internet - just do some research before cloning new topics - first ring was created in Riga in early 90ies by friend of mine as cool wearing ring. Name Anti-Partisan ring was given by some american dealers. Thing you see on pics seems like 25th copy of that ring.
second ring is just a bikers ring in poor casting, probably also 25th copy from copy.


There are less original rings than you think, much less...
