Description: Antique vintage nixie tubes IN-4 made in 1969-1970's years in ex-USSR in city Rivno, Ukraine by factory "Gasotron". This is first version of IN-4 tube with fine small grid and most commonly only with neon gas, while next versions was with neon and few mercury gas. I thought this because its like IN-1 tubes not glow blue on cathodes.
