Silver Mug-Sterling or Plate? Who made it?

[Bob Meyer]

Here's some photos of a small mug that I'm trying to find out who made it and if it is sterling or just plate. I looked at the rest of the site, but I didn't find anything.





Any ideas?

Standard English plate - EP is electroplate. Don't know who the "plater" is though.
