Vintage Pre-War Whitefriars Glass Art Swan - England

Another piece from my childhood via my grandfathers estate. 1930s glass art trinket or candy dish. 9.5/10 condition. No chips, cracks etc only moderate wear on the bottom. There once was a label on the bottom but all that remains now is the etching “made in England”. 8” There were also later, coloured versions made between the late 40s - early 80s however this piece was made pre-war out of crystal clear glass and slightly elongated so it could be classified as a bowl and not an ornament which allowed it to be tax exempt during the early implementation of taxes. My brothers and I always called this piece Nessie or Kelpie as my grandad had always displayed her next to a Lochness print in his study. So the choice is up to your imagination… is she Odette, the enchanted swan queen who is a central character in the ballet “Swan Lake?” or The Loch Ness Monster, affectionately known as Nessie, a mythical creature in Scottish folklore that is said to inhabit Loch Ness in the Scottish Highlands?
