I am struggling to identify the maker of this Georgian silver porringer and would really appreciate any help or ideas. I am not a silver specialist, but the marks seem to be for London, date marked for 1780. I think the maker's stamp is WC, although it is a little distorted so could be WO or WQ. I've also tried turning it upside down so it possibly reads OM, GM or CM but still can't get anywhere. The closest I get is a maker called William Cripps, but he seems to have died in the late 1860s, so don't think it is his! Also, the engraving on the front bears the date 1821 - I'm guessing this was engraved at a later date? Any help would be very welcome!
