From the style it's c1770 and English

Marks appear to be YW or TW , Lion Passant and a Birmingham Anchor .
I originally thought it could an unrecorded early mark of Thomas Willmore, a Birmingham bucklemaker. If the first letter is a Y it was perhaps used to denote Th for Thomas, as Ye was used for The. However Birmingham Assay Office have no record of such a mark and Birmingham almost invariably used dateletters right from the start in 1773. Also Birmingham have reservations over the Lion Passant being a Birmingham punch - although they are the first to admit they do not know all their punches from the early period.
So does anyone have any clues please ? I am assured it is not Cape and it seems as English as fish and chips !
