Hoof spoon town mark of Amsterdam without a visible crown. No year letter, only an unclear partly struck master mark. I do not say that the master mark is of
Abraham
Knobbart, registered in Amsterdam 1668-1718. His master mark
AK conjoined in a shield semi-circular base.
Objects marked with a master mark and with Amsterdam town mark, without year letter were probably made between circa 1710 and 1734.

The crest is unknown to me.
