Hi everyone. I recently picked up this Austrian possibly Austro-Hungarian hand hammered 800 silver tray. It has the Diane head hallmark with a 3 for .800 purity. It is stamped twice maybe three times so it’s not very clear and I cannot tell if there is a letter as well. My question is there is a fairly clear triangular hallmark as well. It appears to be an overlapped WW with what looks like an O or even Q below it. Although I don’t know for sure which way is up. It may be an O or Q over an overlapping MM as well. Anyone familiar with this mark. I was thinking possibly a Werner Werkstatte mark. But don’t see any identical to this one.
I’m not sure how to post pics here.
