Hi John,
thanks a lot!
Yes -- I didn't dare to turn it around to take a base pic because of the weight
Particularly as the top section is fairly thin glass -- another feature which leads me towards Seguso and Pinzoni.
I will submit the correct measures tomorrow, but it is not that big (appr. 20 cm height, 24 cm diameter; I don't know if that was clear in my pic, but the cross section is circular, not flattened like in many Poli pieces).
As far as I remember (I don't have the book at hand atm) the date in the colourway section of the book indicates when this colourway was introduced. No mention when it was discontinued...
I found 3 possible colour combos mentioned which could apply, different shades of red cased in amethyst, though the one you mentioned seems to be the likeliest.
BTW, it looks very nice in fluorescent light as well, when the colour of the casing turns to turquoise
I like your small Sommerso vase, and style wise it would certainly fit in with Pinzoni (apart from the bottom heavy pieces with hotworked thin rim, there are quite a few in the book with thick glass and cut top).
Did you find this colourway in the book? -The colours look quite distinctive, not the usual medium green cased in amber more often seen.
