Shell mark on teapot

I have two silver teapots with brown handles that belonged to my mother. I think they were made in the 70s or 80s. I know they were made in England. The mark looks like a seashell. Any idea who the maker is or what year they’re from? Any help would be greatly appreciated.

That is a trademark of Barker-Ellis Silver Co of Birmingham (UK) as used on electroplate. If you are in the USA they are known there as Ellis-Barker.


Thank you very much.
