Hi,
They display appears to consist of a type of 7-segment gas-discharge tube. This type of tube is illustrated at http://vintagecalculators.com/html/calculator_displays.html#ColdCathode (a little down from the link). At first sight they do look like filament tubes.

They don't look like VFDs to me, there is no obvious grid or heated cathode Are they not numitrons?

No colour film is over the tubes, so those are quite interesting, maybe some type of filament tubes? Have you ever seen something similar?
