Super Funky Perspex or Acrylic Art Deco Dresser Pot's

I bought these quite a number of years ago from a local carboot sale the lady was lovely in her middle ages and said they were her mothers which i think would make them art deco or thats my suspicions i paid £7 and could never sell them i dont know why as i am a chap and have never used them but just feel they have a certain style sadly i have never been able to find anything out about them but thought i would give it a shot on here as i have had some great result with some pottery recently. I am not sure but think they are either perspex or acrylic they have loads of wear to the base's. They are really well put together with engraved design on the inside which really shows through.
The white bases are 9"and 6" square respectively i have as the years gone by thought and hoped they may have been made by a really good English designer.
Any ideas welcome.
