They are labeled as 3H, for tritium, so they would have a 12 year half
life. Any idea how old they are?

Just as a curiosity, I have (I had) some boxed ZM1000 nixies branded
by RTC (France). See attached photos. The box has a label warning
about radioactivity! It probably presents no real danger even if the
tube gets broken. (Unless you break a large quantity of those and make
sure you inhale the gas.) Note that these are no different that your
regular ZM1000's, they were made at the Philips Heerlen factory. (As
was every ZM1000 I have had handled.)
