I've no idea what the stamps are - please see photos and maybe let me know! Strong Art Deco design but I believe the N hallmark dates it to Georgian. Please do your own research. Lovely condition, does discolour over time (sadly this set has lived in a storage container for 8-years) but it polishes up beautifully. We are not dealers, we've just bought beautiful examples of what we love over the years.Collection in person possible in Brighton or Milton Keynes (& possibly London).
