Pinched decanter - Danish, made by Kastrup

Can anyone help with this (pic below).
It's two sides join in the middle like a bullseye, has a ground pontil and I've only seen one other on e bay but they wasn't sure what it was.
I first thought the stopper was a marriage but the e bay one had the same stopper. Any ideas much appreciated.

"Pinched decanter" - so tempted to say, Tut, tut. Put it back.   

Blenko, maybe?

Ha Ha, I paid for it...honest.
the e bayer said they thought their's might be Blenko. Thanks for looking.

9" x5" x3" dimensions.

thanks for that, but the glass maker you site seems to have solid stoppers in their bottles rather than the flat stopper which mine has.

Not sure what you're describing, looks right to me - looks like the one on the far right. Maybe a photo of the stopper on it's own would help.

Did you click on the link to view the four variations of these decanters? They all have stoppers exactly like yours, one (right hand side) is exactly the same shape as yours. I have seen these made in clear and blue, they all had clear stoppers.

This one in clear glass is the design shown second from the right in my original link: https://picasaweb.google.com/Johnmj100/ScandinavianGlass#5543252341222779074
