Elkington & co two makers marks

Hi, i have a silver lidded cranberry dish marked Elkington & Co but the hall mark seems to have a different makers mark that i think is F B OR F R ?
The glass is stunning with raised enamelled butterlies and moths, did Elkingtons use outside designers for items including glass??
I think the hall mark is for Birmingham 1886.
Any help would be most appreciated.

It’s FE and is the mark used by Elkington & Co at that time. FE is Frederick Elkington. I agree that the date is 1886.

Thank you so much :slight_smile: and for such a rapid reply, beautiful isnt it?
