Thanks John, I did find a very similar vase by Henry Dean similar dimensions color but base was polished flat with a wide etched signature the only thing that's niggling in my mind is similar companies used to have there pieces produced at the cheaper mass production glass blowing facilities as cheap as possible then retail them as their own often using various suppliers i have read somewhere. The vase above seems to have been made really well painstakingly polished base and very carefully polished pontil scar as well as good clear glass hard to explain with out holding it. Appreciate the message thanks Dan
