Hi Pip, whilst flipping through my copy of Schranky Vuni just now, I saw some perfume flasks in this same style and thought the info given about them might be helpful in tracking down your piece. The 3 pieces in the book are stated to be Bohemian, 1840s-1860s, but not attributed to any one producer. The companies named as producing this type of work were: Meyr's Neffen glassworks in Lenora, J Lotz at Annin & Debrnik, C. Stolzle on the Bohemia/Austria border, Harrach at Novy Svet. Also by the refineries of W Hoffman in Prague, the WA Hellmich company in Volfartice, and J Grohmann in Chribska, along with others in Novy Bor and Kamenicky Senov regions, and the Jablonec n. N. region - those named were Blaschka und Sohne, and F Unger in Hodkovice, I Palme & Co in Prachen, and J Zahn & Co. in Zamenicky Senov. Hope this helps.
