Numitron tubes

[init4fun]

In my recent haul of vintage electronic stuff I found three of these Numitron tubes . I looked them up and found that the Numitron appears to be a sort of low voltage Nixie tube . Having three I was having all kinds of great thoughts of building some kind of display with them , but when I looked up the actual tube number "DR2020" I found that instead of having all the segments a Nixie would have had , these tubes can only do + - and the number 1

Oh well , even though they aren't all that useful I figured I'd post them up for folks who may have never seen one ...
