remains of old stock with skulls in black enamel was recently sold on Latvian auction. So we can expect soon showing up more "period" rings in good condition.
Yes, I saw this plates on antik-war.lv forum. Strange is that skull has black eyes and plates with latvian coat of arms has dark red not transparent enamel without dashed lines design under the enamel. As I remember correctly owner told me that this plates are not silver - which also strange.
