As an ex air trafficker in a very distant previous life I still recall the numbers wun, too, tree, fower, fife, ate, niner etc. ... Could never add two numbers together to make thirteen (wuntree) or similar.
When recording the ATIS the QFE might be 1000mb but I used to have to record "wun zero zero zero" although I would bend the rules ad-libbing "one thousand" millibars.
And of course the lower runway numbers were "zero nine" or similar, always the zero.
