From the dimensions (height/width) I´d say they are ca. 20cm / 8" tall and should be WVZ
(abbr. for Werkverzeichnis = catalogue of works) 445, designed in 1951.
If these dimensions shouldn´t match, just let me know the height, please.
They can vary by quite a few mm BTW.
The glassworks´ name for this colour is ´turmaline´.
Cheers,
Dirk
