I think this sort of 'thistle head' shape is a definite 'deco' shape, and has enough wear certainly to take it back to the late '20's or '30's. No marks - stands about 6"/153mm tall, and has a good quality ground/polished central pontil mark on the base. It doesn't react strongly under the torch - but there is a definite glow. The white sort of internal flecking is attractive - maybe 'pulled' up possibly - but whatever, is unusual in the way that it runs throughout the piece (reminiscent of some of the Italian thread like decoration). Probably a non starter for an attribution, but thought people might like to see it, and thanks for looking.
