Two sign indicators and one numeric tube. All tubes have been tested with a homebrew switchmode supply built to drive Nixie tubes. One of the sign tubes is obviously heavily used, the glass is darkened in the front.
All three boards include a socket with the full pin count populated, which may actually be more valuable than the Nixie tubes, especially the sign tubes :)
There's also a great mix of really old TTL on these boards. Some of it is packaged in blue plastic DIPs made by...Sprague! I didn't know they *made* ICs. Appears to be standard 7400 series TTL. The board with the numeric tube includes a white ceramic TDD1100 which appears to be compatible with the usual 7441 or 74141 Nixie driver ICs commonly found in 1970's equipment. Tubes are tested, control boards are not.
