Handblown Art Glass Vase Help

I would guess this is a single flower vase. The hole at the top is very small measuring only 3/16" in diameter with an uneven lip. It has a signature on the bottom that appears to say "Brienz" which is a town in Switzerland, however when it comes to deciphering signatures it's a crap shoot. The style/shape looks mid century Scandinavian to me. The dimpled sides are connected on the interior. It stands approx. 7 1/2" tall. The blue has a bit of iridescence to it, especially around the bottom. Just a random art glass vase or something better?

I guess it's possible it was made by a private individual glass blower from Brienz. Just wondering why they would sign it (and date it) with Brienz, and not their name. Brienz has a population of 3000 people and is known for wood carving. I'm still not convinced it says Brienz.
The nearest (and only) glass factory in Switzerland is in a different town 32 miles away. The "Glasi" glass factory in Hergiswil, Switzerland. It didn't come from there.

 

The sig looks like Brienza '75 to me so I googled Brienza and found Barney Brienza who taught glass blowing among other things and the date sounds right. Maybe?

My Dad made that, Barney Brienza. He was born in Orange, New Jersey he now lives in Yuma Arizona! Enjoy!
