Unfortunately the only marking is the one on the front of the base.
“Unfortunately the only marking is the one on the front of the base.”
Often export markings may include the maker’s mark, 90 would be purity signifying sterling and often a third mark if done by an apprentice or something.
Also don’t rule out Native American origin and often the markings on these could more difficult to identify but I have seen some beautiful pieces but I can’t see enough detail from video to recognize anything.
Best of luck
