Looking for maker of Kopenhagen spoon 1682

[Solpar]

Trying to confirm the maker of a Kopenhagen spoon dated 1682. The former owner attached the name "Johann Wahlblom". Can anyone confirm this maker and add further information or tell where I can look it up, please? He's not listed in Rosenbergs "Der Goldschmiede Merkzeichen". Thanks for you help.

I understand why Johan Wahlbom comes up. He is mentioned as master 1651-57 and as 1884-1689 as hawing workshop in Købnagergade. However his marh has a different cartush. Not
the sides they are without the (at the sides)

Citymark of Viborg Wiborg 16hundreds was also WB - but not the cartush as the one shown by you.

Wahlbom has a bowl in Bornholm museum and a spoon at the National museum.
" other items attributed him i smentionen in the book, with no place.

In 1689 he is mentioned as a former master.
