Huge ruby red blown glass decanter with handle

To be honnest with you I have no idea who the designer is. I don't think it a murano, perhaps a smith But I think that is a viking glass The rubi red blown glass is so deep, the tone is so perfect. I have no idea who the designer is. It necessarily dates from the 1st half of the twentieth century and necessarily handmade... I would even say a unique piece. It is in perfect condition. It has an impressive size of 70cm in height. The beak is as long as the body.
