Hallo Adam.
It looks like an Aseda dogbone-vase. Other glassworks had different bottoms, different
size and number of bubbles and some had no bubbles at all.
The Aseda dogbonevases came in 3 different sizes. The smallest came between heights 160-180 mm,
the medium sized 185-220 mm and the tallest 250-300 mm.
Hopefully will this help You out a little.
Best regards
