Any help with finding the ui font?

Chalet London 1960  Vorgeschlagen von thafitos 


Franklin Gothic  Vorgeschlagen von steelsmiter 
Helvetica Neue 45 Light  Vorgeschlagen von SirParadox 

Of the fonts already on my system, I found Franklin Gothic Medium does well to emulate it for the RPG manual I'm writing... although you might want light if you can find it.

Grand Theft Auto V’s UI font is called Chalet London Nineteen Sixty.
