Nixie tube manufacture in Tesla

This video comes from Tesla company archives and was presented on exhibition called “(Un)forgotten Tesla“ in Valasske Muzeum v Prirode in town Roznov pod Radhostem - town where Tesla originated from. As far as I know, it is the one and only video showing a nixie tube manufacture. I would like to thank to Valasske Muzeum v Prirode for making the video and for keeping it for future generations.
