Hello,
This is a lovely vase - grey colour, applied trails, nicely polished out pontil with lots of movement marks, 21.5cm tall and weighs 1.6kg; its from my favourite car boot sale - I must post pics of what I buy there, it's insane.
Annnnnnnnd.....cancel the request for info; I posted this here, thought 'Perhaps it's Scandinavian', had a quick google and lo and behold, it's a Skruf vase by Bengt Edenfalk.
