Hi Keiran,
Lucky you finding it in a charity shop - I paid £32 perhaps about 8 years ago for mine, in an art gallery!
I did nag and nag them for more information about the maker, on more than one occassion - first when I bought the piece, and again, after Frank saw mine and fell in love with it. Ziltch, apart from this:-
The title of the piece is "Golden Rain". (This was typewritten on the sticky label on the box. This was all that was written on it.)
Info. from the gallery was that it was made by a German girl, working in Oban.
As it is lampwork, this would not have required a great deal of equipment or even a proper studio. At Frank's suggestion, I wrote to a glass worker (engraver) who had also worked in Oban, but it was a good while before I recieved a very kind, but sad letter in reply from his widow. It had taken some time for my letter to be forwarded to her. Also sadly, she was unable to give me any information about any German girl doing lampwork there, and the trail seems to have gone completely cold.
Sorry I can't help you more. Just enjoy the piece (- or sell it to Frank, so he can!)
It IS lovely.
