which shows to prove the lemonade glass was made between 1918 and 1930 and bears no relation to the decanter.

pantograph etching came into use after 1918 so your de canter may be younger than it seems.

I am currently working with a small industrial heritage museum in Bergdala, Sweden.
We have a pantograph (from Kosta glassworks), but do not really know its history (and the Kosta archives are currently buried, waiting for organization and, hopefully, digitalization (sp?)). Anecdotal evidence dates it to the 1890-ies; one of the pattern templates are for IX Desutches Turnfest Hamburg 23 - 27 Juli 1898 (which implies the machine was in use before those dates, we think). (Can't find a way to insert pictures, but they can be found at http://bergdala-museum.blogspot.se/2016/03/ix-deutsches-turnfest-1898-igen.html *not* a good photo, unfortunately)

There is also a picture in a book (Steenberg et al: Modernt svenskt glas, 1947 ) of a glass  called "restaurant glass from Kosta, 1890ies" depicting  a glass for Hotel Cecil (London, UK). We have the template.

As all/most of our evidence is anecdotal, I would be very interested of sources for the history of the pantograph as a machine for mass-producing patterned glass.
Can you point me to any literature or other sources?

Kerstin in Sweden - who is also interested in the terminology of etching - "wheel etching" compared to "needle etching" compared to "guilloché"?
