Love this vase I've just acquired

. It reminds me of some Flavio Poli pieces, except that the heavy clear base is more angular and not rounded.
I did think it might possibly be Scandinavian and a Nils Landberg piece, but haven't found a match. It screams 1950's IMHO.
Very heavy at 1.8kg, 14" high with a smooth pontil mark. Rounded rim. Not uranium glass.
It needs a good clean - when I find my magic balls.
Any ideas would be much appreciated.
