Hi all,this is my favourite glass for wine,and my wife's,it holds the right amount for a early evening relaxer and feels right,however I was just browsing through absinthe glasses and I think there are similarities to some I've come across,it's 15.5 cm in ht and 7.8 we,perhaps a bit small?,it has a shear mark to the base and good wear so I've always had it down as about 1870s?i think there maybe a little lead ,but not that much,any thoughts .
