well, just as you all had me coming round to it being a lamp base, I just stuck my nose on the brass top,
and without a doubt, I can smell perfume!!
Definitely not anything i washed it with or a soapy smell, but a distinct ,strong and rather nice perfume

Im sure its a female fragrance, I will ask some of the fairer sex if they recognise it.(It is familiar)
Im 100% sure now , its a perfume bottle!
I do agree that its probably c 1950s and from Murano.
(any suggestion of a maker, welcome)
Thanks to all,
Andy
