Wow thats great! Thankyou very much. Its obviously been a treasured piece to have survived this long without any damage, its like new!
I have wondered for a while what it could be and couldnt find anything like it, obviously looking in the wrong places. I bought it from a carboot sale for £2 some time ago.
Off to research Sowerby now! I tend to buy all sorts of glass from carboot sales just so i can research them. Its my way of learning.
Many thanks again for your help.
