Got it.
Bagley.
Andy's "Miller's 20th Century glass", p101, bottom right. I'm copying out relevant bit of the caption under a handkerchief vase for you.
"Pressed
Wild Oak Handkerchief vase. Probably designed and produced in 1975, but when Bagley ceased making fancy glass in 1975, the moulds for Wild Oak were transferred to Rockware who produced it for a short period.
15cm(57/8in).The centre of the base is impressed with a large White Rose, the symbol of Yorkshire."
The moulds being used in two different places might well account for the difference in the quality of the metal used.
So perhaps yours is Bagley - but I've only ever seen Rockware.
