Identification of Crystal Wine Glass

I am looking to identify these wine glass that my father inherited from his mother. Unfortunately throughout the years some of the glasses have been broken, and I am therefor trying to figure out where these glasses originate from, so I can try to track them down.
They have a very big affectional value to my father, so I really hope that someone is able to help me out! (This is the white wine glass, but they also exist as red wine, dessert wine and champagne glasses with the same design)

Fingers crossed and thank you!
