Matt, you forgot about the B-7031, B-7032, B-7037, B-7038 (and their
national Electronics versions), and the NL-934 (not sure if there is an
equivalent Burroughs tube). All 50mm tubes ;-)

For the tube on the far right, how long does it take for tubes to
darken this badly?

At some point, artisan nixie tubes will be cheaper than some of the
largest NOS tubes that rarely show up. Of course, to get a decent
service life, either giver pills need to be found or created or there
needs to be some other method for adding Hg vapor after the tube is
sealed from the vacuum pump.
Numeral height:
Nixie Rex (panaplex) 457.2mm 18"
