Please help me to identify this mistery hallmark!

Hi friends
Please help me with this
There is a beautiful mug with this hallmark
very strange:looks like lion for sterling silver,date letter and Sheffield.But there are no maker.s mark(only a B?!) and hallmark for Sheffield looks strange
thanks a lot for your help!

You are right to think it looks strange. It is not an English hallmark although it’s clearly meant to look like one. As it doesn’t have any clear and honest indication of silver quality I think it is much more likely to be electroplate.

(I have deleted your duplicate post in the Photographing Silver section.)

Possibly Pewter?

Thanks very much for your opinion my friends!
