Last one today I promise... here we have what I believe to be another Hineri or Kamei vase. Very heavy and 210mm high. Some wear on the base (see pic).
Spent ages wading through all my Czech glass references until Lustrousstone pointed me in the direction of Japan. Although the colours of this one aren't as rainbowy as the other Japanese vases I have (hence my Czech search) it does have a similar multi-bulged base. Your views appreciated.
