I have some information on Eric White and I attach a flyer which illustrates his work and gives some info. The V&A purchased 3 bottles in 1980 one of which is a crown, two of the bottles remain on display in the glass section. The silver jubilee crowns were in several different designs, there was a limited edition of 500 of each design.
According to information in the bottle boxes Eric White was born in 1925, lectured in glass at Isleworth and had a studio at Hampton Court/Esher. Unfortunately there seems to be no information on him anywhere on the internet.
