I expect someone is Russia still makes them...

I did some digging. Dekatrons are still available in Russia, but with a
different base, so need an adapter. There's also a surprising amount of
the originals on fleabay.

The Dekatrons used by WITCH are the GC10A and GC10B, the Russian
compatible is OG-4.

From the restoration blog:

"I am looking at the possibility of using the more readily available
Russian OG-4 Dekatrons as a direct replacement for the GC10A. OG-4's
seem more similar to GC10A than GC10B (low strike voltage) although they
have a different pin-out. No problem - I adapted the base of an OG-4
with epoxy and an octal base from some unknown broken valve. An
advantageouas side-effect to this is that the OG-4 is now slightly
longer (but still not as long as a GC10A!)"

This is the blog of the restoration, up to May this year. They make
fascinating reading. I'm posting the direct links are they're hard to
find from the home page.
