Hi,

Do you know some information about this theapot? Country or silversmith?
I think Dutch silver, but I don't know sure.

Thank you in advance for identify.

Hi,

Dutch pseudo/fantasy marks and the Dolphin mark.

The Dutch dolphin mark; the 1859 duty mark for new unguaranteed objects of national origin. This mark was used on all new silver objects below legal standard of fineness, those with non-precious metal additions, and on new heavily gold or silver plated objects, as long as the average precious metal content after melting with the base metal was at least 250/1000. It was also struck on rejected objects which had been submitted at lowest standard of fineness. In that case the maker had to choose between destruction or ‘unguaranteed’ marking.
