Hi Michael,
very interesting vase, looks indeed very "Gangkofnerlikely" but I regret I have never seen this shape before.
The colour looks very much like Hessenglas-champagne too, but the shape is definately not documented in the Hessenglas-context so far. I´ll show the pictures to former glasworkers, maybe somebody recognizes it. Every now and then a new Hessenglas-Gangkofner-shape appears which was not documented so far.
But for shure there were also other companies producing in Gangkofner-style. I bought one asymetrical perfume bottle
in this typical Gangkofner-style, which I found some time later again with an "austrian" label on it, which I have not identified yet.
Your vase may very well be from austria too. I´ll search for the label-picture..
@ Dirk: very nice collection, especially the "neurot´ische schwangere Jungfrau" makes me jeallous..
