Anod IN-1  
Written by Accutron on 2017-03-20  

The Anod IN-1, the USSR's first mass-produced Nixie tube, is a large end-view device with a 18mm digit height and an obscure 11-pin phenolic base. Unlike most Nixie tubes, the IN-1 fill gas contains no mercury, a circumstance which dramatically shortens the lifespan of the device to only a few thousand hours.
