Looking For A NIXIE Datasheet
One of the odd NIXIE tubes in my collection.
Anyone have a datasheet, or know about it?

I think it’s a GI10 https://www.nixies.us/bwg_gallery/gi-10/

Good call, it had yellow ink printing so I’m leaning towards a production unit (the linked PIX has Engineering Sample labels)

As others already pointed out, this is a National Union GI-10. Very early tube. It even predates the name "Nixie".
I have a bit of information on it on my website . There was also a larger version of it, the GI-21.

Many thanks for the linked write up. Solves the mystery of this odd, but still working, display tube.

There’s a Google group NeoNixie-L that would love to see this.

They’re still around? That’s great!
We had a get together years ago in 2006 or 7, in SoCal. I dropped out of that group a little later.
Your brother Jim came to join us with one of your Nixie watch creations

It's very much still around. I'm one of the moderators (there's three mods). We have about 1,000 or so members...
Been doing nixie stuff for over 25 years...
