Direct quote from the 'read me'…
"Disclaimer thingy: This is an enhanced version of the
original "QUAKE" font I found on the web. The stylized
"Q" and all other logos are copyright id Software (the
greatest game makers on the face of the planet)."
So with VERY complex ownership, it may be worth considering using a different font…
Build a 'ligature' of your '100' combined glyph by cutting, pasting and scaling and park it some where easy to remember in day to day use is the easiest way to do this. Creating a proper ligature, so when you type 100 there is a dlig lookup that automatically spots the (three glyph) 100 and substitutes the single reduced width '100' single glyph is the other way. Seemsa a fairly comprehensive Tut here for creating ligatures.
Looks like a variant of this, but if very old quite likely it was a 'pre-digital' cut (filmotype or similar)
Could be a bold condensed Trade Gothic…(there are a couple of different cuts)
This dates to 1974 (or possibly earlier), so the best you can hope for is a 'revival' of the typeface used.
Here's one, that will not be a bad fit, with a little scaling…
If you google 'Illustrator Tutorials, Blend Tool' you should find links to how to do this.
Drop the 2 into 2 layers in photoshop or similar image editing app and set the transparency of the top layer to 50% or lower so you can see through it to the layer below. Scale the top layer to match the bottom and you should be able to see the differences and or similarities. It's often better to colour one of the layers so you can more accurately spot a match or not.
Check the individual fonts used in the flyer for their licences. If all are free to use for commercial purposes, you are home free, if not, contact the individual font authors. Naming which fonts are used would get you a more definitive answer.
I think the current system font for iOs devices is San Fransisco. The previous default was, I believe, Helvetica Neue.
