Thank you for the request here.
Please allow me some time to look at the images.
The EP BM stands for Electro-Plated Britannia Metal.
I would need to see just a tad bit more of a clear, in-focus image of the maker mark to try to make a match. I can see a J and an F in the triangles, but the letters I see may not be correct and I need to be exact.
Yes, this is very helpful - please allow me some time to make the mark match for you. ~Nora
Yes, eureka! That is correct. Friedman Silver Co from Brooklyn, NY circa 1920.
It is done in a Dutch style and made of electro-plated britannia metal.
On today's market, expect to garner $30 - $50 each. The suggested insurance or replacement value is $65 each.
