Many thanks for your reply Paul H, it is really interesting to hear your views and I will certainly take that line of enquiry.
I bought this from a local 'museum' ... it is actually an old gentleman who has been an avid collector all his life of anything and everything, who's wife insists that he 'get rid of some junk' - he hates selling anything and so his prices can be pretty high, since he really doesnt want anyone to buy anything - he just likes to chat. His shop is soooo full of stuff that I visited 3 times before I realised there is a car inside the place, full of and covered with all sorts of collectables!
He didnt have any idea's about where the vase was made but thought it was 'probably quite new, no older than the 60's'. I was looking for a 'lump' of something, quite large to fill a space in our house and found this, which I really fell in love with.
