need help identifying marks

I have a large silver punch bowl, large circular tray and cups that belonged to my great-grandmother. Other than the marks (see link), I have no idea where they came from. I’ve looked on-line but cannot decipher the marks. Any help out there? Thanks! … ermark.jpg

I’ll describe as best I can in case the link above doesn’t work.

From left to right:

  1. Trefoil/clover(?) over a smaller right-facing lion
  2. Crown over a smaller 5-pointed star
  3. Left-facing lion over a smaller right-facing lion

There are no other marks on the pieces.

This is a silver plate mark of E G Webster & Son of Brooklyn.
