yes a very old pattern.. A MM ring will always have at least one or combo of:
- A skull,, a hour glass,, a scythe,, stars,, a half moon,, a sword,, and occasionally a crucifix.,,a swastika regular or reversed ..
Benten,,,what are those marks your showing us? some type hallmarks.....
- And Ric,,,is the content mark on your Pz skull ring behind the skull in a square??
