hi Chloe!
possibly walther. i´ve seen lots of this or at least very similar designs
on flea markets round here (walther is very close), but that´s of course
just a hint.
a quick search on ebay didn´t lead to acceptable (attributed) results either.

here´s a candlestick (which indeed is a bit scandi-"inspired") with the
same surface structure as your bowl, which i suspect to be walther, too.
hopefully someone will be able to give more than a guess...
