Can anyone help me identify these marks on this silver & blue cobalt glass salt cellar? It is marked J.E. Caldwell which I understand was a silversmith/jeweler who opened a firm/retail store under the name JE Caldwell. I believe the marks are British but have searched and searched and cant seem to find a match on all the marks in each of the shapes on this item. Any help is much appreciated! The last mark isnt quite so clear (sorry!) but appears to be a lion or possibly even a cat. ?
Here are some photos of the item and marks:
Thanks in advance for any help and info provided!
