Need help identify maker and year

Hi. Have a beautiful English sterling vegetable dish. Can not read the maker mark. May be somebody can recognize it? Think it is 1912. Please correct me if I am not right. Thanks. Marina

This is probably a mark of S Blanckensee & Son Ltd , namely this one:
SB+SLtd-SBlanckenseeAndSonsLtd
(or a slight variation of it)

I can confirm that the year is 1912.

Phil

Thank you Phil. Have a happy Holidays
Marina.
