Thanks for your very comprehensive reply, I now know all about this scent bottle and am really pleased.
I would also like to thank all who have taken the time to help with my queries on this item, its very good of you all to help and is very much appreciated.
I have collected glass items for a long time without really knowing what they are, just bought them because I liked them. I am now slowly trying to find out exactly what they are. This site is really helpful and everyone seems very willing to share their knowledge, thanks again.
Regards Mick
