It's possible, they did stamp some NL-5991s as "National Elecscronics",
though I think it might be something like a different gas mixture, I had to
use 250v to get multiple segments to light (I was using cathode resistors,
so dunno what's up with that)

Could it be something as simple as when they stamped the tube it was a typo?

 Is it the same in as much as it has the same segments (difficult to

this tube indeed contains mercury, though I think normal 5971s do too, the 
top and bottom horizontal segments are still only one segment each, and the 
middle vertical line is still only one segment aswell.

I have B-5971 and NL-5971.
I'm currently having a renovation. My collection is buried in boxes.
I'll see if it makes a difference this weekend.

Re: [neonixie-l] Re: B-5972

[Nicholas Stock]

Are the central or top and bottom segments still continuous in this
version? I could imagine that an 'improved/subsequent' version may copy the
7971 configuration as the 5971 is only a 13 segment displayIIRC.

Maybe 5972 is mercury version of non-mercury 5971?

I have one of these aswell- at least, it was sold as a B-5792, the part 
number is sort of smudged, 2 of these showed up on ebay from the same seller 
recently so I imagine this is the other one, it has the same segments as B-5971
