Hello Keith
One of the basics in Northern America is: If the item isn’t marked with »
925« or »
STERLING«, then it’s »
Plated«.
Well, there are some exemptions, when it is made e.g.
before 1860 — time of »
COIN« silver.
If you take the time, to read former topics, then you would get some more experiences. Yours ashtray is »
Plated« -
for sure; you could see the basic material, a Nickel-silver-alloy. Please read:
http://www.925-1000.com/a_platenumbers.html Well, that is basic information on European (German, France, Russian) »
Plated« theme.
http://www.925-1000.com/silverplate__menu.html I couldn’t tell you, who were the maker —
the maker’s mark I don’t know. But our American Contributors I think could assist you well.
Kind regards silverport
