Sheffield Horseshoe help with date & makers mark

[joelthall]

please help me identify date & makers mark.

[SilverSurfer]

The closest fit I see for the date is 1946-7 (capital print Arabic D with serifs, shield pointed at bottom). Sorry, I can't help with the maker, too recent for my references, but seems to me the mark has a later style befitting the date I've indicated.

Thanks for the help. My reference books cover only much older date marks.
