This is very interesting. I took photos of a similar pump in 2003, also
in France. You can see that the second digit on the price per litre is
also a large tube, because they moved the decimal point when they
changed from Francs to Euros. You can still see the old decimal point
covered with black tape.
Since the pump in your photos has a small tube for the second digit, it
looks like they replaced the tube after changing to Euros. Does anyone
know which types of numitron they might be, and if the two sizes use the
same socket?
I also have another photo from 2002, where the display looks like a
regular 7-segment VFD, but with a weird translucent sheet in front of it.

My uncle has a very good nixie multimeter which he still uses as his
primary instrument, because even after all this time, it's still
ridiculously precise, without recalibration for decades. I also own a
nixie multimeter, but it's lower resolution (Philips PM-2421 with ZM1000
tubes) which I still use occasionally, mostly for testing batteries. I'm
sure there are a few labs which still use instruments with nixie tubes
or panaplex displays.
And my school still have some counters and timers for physics class
which used nixie tubes, although I'm not 100% sure they still use them
(they did use them at least until I graduated in 2006). Since these
devices are purpose-made for demonstrations in front of the class, the
nixie tubes are quite large, probably 40 or 50 mm digit height.
