I have a recollection that "Cascade Glass" was a trade mark used ( with a black and silver label of a fountain cascading down by one of our pressware comeptitors now defunct. So it may be Waterstone Glass of Wath upon Wear near Rotherham, Wodd Bros, or Trent Valley.
I have not seen a catalogue for ages, and I left my archives on defunct British Glass to the Broadfield House Museum in Kingswinford, near Stourbridge. A call to Roger Dodsworth the curator ( and author of "British Glass between the Wars" may solve the mystery!
The blue looks like Waterstone who made mainly bottles and ashtrays and a few things like eye baths in that blue. (See Eyebath website for Woods as well!)
Sorry not a definite solution but a lead perhaps...
Fancy giving away my archives in July and deciding in September to start collecting British Domestic Glass! Doah! What a plonker!
