I think that display was built using modules like this:
http://www.decadecounter.com/vta/articleview.php?item=511
I see them on e-bay from time to time under "in-line readout", but they're
rather expensive and you'd need quite a few, If you can settle for 7
segment, a modern display you could use is:

Or, perhaps these:

But, 7 segment just doesn't quite capture that retro feel, IMO.
