If it was ever owned by smokers especially when it was a working set nicotine tar can really yellow/brown a surface. Ammonia glass cleaner (wet surface and let it sit a minute or so) and or Gojo tend to do a good job of removing it.
I'm pretty sure the 21" sets are supposed to have a sort of oliveish tint to them....Zenith roundy color sets (that use a glass safety lense) have the same tint to the glass and the mask paint.
