Hi folks! I bought a couple of boxes at my local auction 2 weeks ago, specifically for a 1949 William Wilson vase which had gone un-noticed by everyone else. There was also a piece of Royal Bohemia, an art nouveau brass & elm ink blotter & a bunch of other stuff (
£25 & half my Xmas pressies bought - wahey!) Anyway, also in one of the boxes was the vase shown below. It's approximately 220mm long, 140mm wide & 160mm at the highest point of the rim, which drops slightly at each end to give a wave effect. The base is flat and polished, though scratched with age. I guess it weighs somewhere between 3 & 4 Kg.

I only have these two photos & my digital camera is out of action, but I'd be seriously grateful if anyone can help me identify it.

The second photograph includes a Whitefriars jug in Kingfisher colourway, purely for comparison as it is
identical.
I've only been collecting glass seriously for just over a year, so my reference material is limited and my knowledge even moreso! I'm itching to know where this piece originated. Someone put a great deal of effort into producing this - I've scoured every book in my local library, every website I can think of, so pleeeease can someone help me??!!!
