Thank you both Tiger and Max
Tiger: Interestingly Alexander Hardie Williamson designed for Ravenhead in the 60'sso although I haven't identified the particular design it looks promising. I have a leaflet about Ravenhead glass and looked at that first but it only showed the tumblers with the splish/splash designs.---and I only have the 2004 Millers collectables and its not in that. Ho hum!!
My daughter should have been a teenager in the fifties/sixties as she has her name on these glasses and my fifties bar and other bits and pieces I have from that era i.e. Pineapple Ice Bucket but I will hold on to them for the moment . Trouble is my house is gettting smaller and smaller
Thanks for the input will keep looking.
