Definitely Scandinavian, probably Swedish but I don't have my Swedish book with me till Tuesday and I don't see these mark online anywhere. It could also be Norwegian
Yes Swedish, I believe so too and the town mark for; Karlskrona, early 18th century. Prior the introduction of The Swedish State standard mark with the Swedish Imperial crest, the three crowns in a three-pass in 1752. The year letter Z (?) around 1736-1737(?) https://hu.wikipedia.org/wiki/Karlskrona See: https://www.silverstamplar.com/town-marks.html
Thanks to my Swedish connection herewith the maker's mark.The maker's mark reads IMH; for Johan Michel Hofner, registered in Karlskrona 1730- died 24-8-1739
without hallmarks I would date this sop-ske at an earlier date. So he made this in an old tradition looking backwards in time. Old habbits and traditions live long after we would assume new style.
A bit more. The second mark from the right (italic L) is the year mark for 1735 and the last mark, the "flower" is the alderman's mark for Adam Münchenberg 1728-1736
