I think that (based on the current supply of nixies), if I was to design
and build a new clock right now I would use IN-12's.

The one nixie clock I've seen on Kickstarter took a different angle on
things...

It is 4 digit (IN12's) but that is just one of it's features.
Personally I prefer 6 digits, but each to their own. My only comment
on IN-16's is that they seem to have a high failure rate (digits start
glowing pinkish then die over a period of days to weeks....)...they're
a pain to change too!
Best of luck in your search, but a bulk buy probably won't be cheap now...

Assuming I can determine it's feasible at all, my plan is to do a
Kickstarter campaign; I am tentatively imagining somewhere in the
neighborhood of 200-300 clocks, so with 4 digits each that'd
be 800-1200
tubes. If the Kickstarter campaign were to really catch fire
(hey, never
hurts to dream), it could be a lot more, so one of the things
I am trying
to find out is what the effective maximum number available are.
Do you have a photo of your dad's clock we could see?
These days, the clock itself is not very interesting; it's the
packaging that people go for. And you will get a lot of argument
about taste and style, as these are highly subjective. You've
already heard a few arguments about the number of digits.
The 5870 tubes are rather narrow, being designed for use in
12-digit calculators. That's why I use them in my wristwatch.
Unfortunately, they don't look as nice as the other tubes that are
a bit larger in diameter and have better-proportioned digits.
If I were doing this, I'd build ten clocks and see how well they
sell, then make 25 more, etc. There is no reason to commit to a
large quantity of parts these days, given the availability of
prototype PC boards and CNC machining. You should be able to find
50 5870 tubes from a broker pretty easily, although the price
won't be super great, at least you'll only be out 50 tubes if it's
a bust.
