RARE - 1960’s Friden 1114 NIXIE TUBE Electronic Calculator - TURNS ON - made in Japan by, I think Hitachi, it was one of their first electronic nixie tube calculators - in original carrying case (suitcase sized - its huge and heavy!) - comes with instructions and keys - also marked Singer as they bought Friden, so many companies involved with this one!! Very clean looking and all tubes light up - sometimes it worked, sometimes it did wacky things - but the fact that the tubes all work is the home run here!! Very rare early electronic calculator. (Instruction booklet says model 1113 but this is a 1114, very similar and I guess that's why they issued with 1113 instructions)
