Hi Guys
This is a great idea, so here is my first post with photos I hope!!
This vase is 11.5" high and five" in diameter at the to on the base is 269. from the mould and printed is DEK . 40 not sure about the D it could be B or G.
I emailed GinFor's Odditiques.com with photos and the reply was
It's possible that DEK 40 stands for Dekor 40, which would make it
German. Otherwise, you'll have to stumble across one with a label or
more marks to ever be certain. Still, I think I would lean toward
Carstens-Uffrecht.

I also emailed outernational but did not recieve any reply
Can anyone add to this, I think German
