Nixie tube and other older tube calculators

Singer Friden 1160

This CRT tube calculator is one of the first calculators made by Singer in 1966 and has CRT tube display. It is an extended  basic calculator. Unfortunately it doesn't  light up. It could be a small thing, as I have no technical knowledge. Serial number  01649.

This item  is in a good optical condition, only the plastic keyboard cover is partly broken at the bottom edges.
