Thank you, John! I wonder how I missed that when I searched the board? Great whale, by the way.
F.M. Ronneby, Konstglas it is.

Edited to add: 10 minutes wiser, searching google images for "Ronneby fish" is much more effective than searching "Konstglas fish". I have found a smaller version of my fish, signed and labeled. I've also found Ingela's post on another board with images of this fish as well.
But now why isn't my item signed?
