'Kuttrolfs with raspberry prunts appear to be in the minority when it comes to variants for this type of decanter which, as a type, has a very, very long history.
Designs similar to yours, showing the raspberry prunts and the cog-wheel pattern down each corner, are shown in McConnell's 'Decanter' book - these are indicated as Aalborg Glasverk c. 1870, and Holmegaard c. 1923 - both Danish of course.
The drawings in the book show stoppers which also have the prunts, although notice yours doesn't, and there's always the chance your stopper might be a replacement - I'm not suggesting it is, but simply saying that the examples I'm looking at do have them.
Just possible that the Aalborg glassworks made these things more commonly in the C19, copying the German standard form, and adding the prunts for decoration - although apparently the Romans were knocking them out long before that

Am I correct in thinking that Holmegaard examples are more common from the C20 - I'm really not sure.
Wouldn't like to make an attribution closer than these two Danish factories, but at least gives you a direction to look in. Perhaps Ivo is able to add something more useful than my comments.
