The Nixie tube is a vintage display device which had been used until 70s
when it was replaced with LED displays. The complex knowledge of
manufacture of Nixie tubes literally died with tube factorys engineers,
glassblowers and machine operators.

Wikipedia: The early Nixie displays were made by a small vacuum tube
manufacturer called Haydu Brothers Laboratories, and introduced in 1955Â*by
Burroughs Corporation, who purchased Haydu. The name Nixie was derived by
Burroughs from NIX I, an abbreviation of Numeric Indicator eXperimental No.
1,Â*although this may have been a backronym designed to evoke a mythical
creature.

Hundreds of variations of this design were manufactured by many firms, from
the 1950s until the 1990s. The Burroughs Corporation introduced Nixie and
owned the name Nixie as a trademark. Nixie-like displays made by other
firms had trademarked names including Digitron, Inditron and Numicator. A
proper generic term is cold cathode neon readout tube, though the phrase
Nixie tube quickly entered the vernacular as a generic name.
