Electromechanical Relay Nixie tube clock 1950’s cold war replica part 1

So I’ve decided to make nice big beefy 1950’s replica of Nixie clock inspired by old HP gear. I will use XO for start and later 10Mhz OCXO. This clock is basically tribute / inspired by HP model 571B mechanical clock and late 50, early 60 HP frequency meters, generators and other gear
