Crystal ID Help Please

This lovely crystal belonged to my great aunt (aged 89) - but I'm afraid I don't know how long she has owned it. All I know is that it is referred to, by her, as Lye crystal. It is unmarked; nice and heavy and all etched with grapes and vines. There are wine glasses, champagne bowls, brandy balloons etc etc. I know that my grandfather was born in Lye and I know that Lye is near Stourbridge - that's all the info I have. I've been looking on google images to no avail. Any ideas please.

Try contacting Broadfield House Glass Museum, they hold a lot of the records for all the various Stourbridge Factories. Also Will Farmer at Feildings Auctioneers in Stourbridge has been helpful for me in the past.

Thank you Davee, I shall certainly give them both a try.
