I don't know the maker, but I have a blue one. Many years ago I showed an image to somebody (was it Ivo?) who suggested Polish as a possibility for investigation.
Mine is much the same size and weight ... height 15 cm, max width 12.7 cm, weight 1.34 Kg
Twelve ribs with a slight twist; translucent blue (no bubbles); iridized all over but appears dark blue or silver in various parts under various lighting. The iridescence shows as a sort of "gold / yellow" mainly visible on the neck / shoulders, but again the effect differs according to the lighting.
