Hi Davem, It is an attractive piece of glass, and appears, as you say, to have some age to it, and is well finished off with a neatened and ground pontil mark, so I can see why you might think it was Murano.
Kane, your brief answer has left me baffled....usually when one of us is positive about an attribution being incorrect, we at least explain where our doubts lay and in some cases even suggest further possible makers or avenues of research.
Davem is a relatively new member, and has in previous threads been very complimentary of our GMB, so maybe Kane, you or someone with more knowledge of glass vases than I have, would give a little more helpful direction to him?
