This is an electroplate mark. It reads [D] [&] [H] [fleur-de-lys] [B] [EP] which is a trade mark of Deykin & Harrison of Birmingham.

Thanks for your reply.
Upon further review and inspection, the 3rd character appears to be an "E’.
I’m still not sure what the first character is. Perhaps “R’”
I don’t think it’s a “D”.
I’ve attached a clearer picture. Let me know what you think.
Thanks
