I think that there was a small plastic jewel lens mounted in that hole. I don't think that they were anything that fancy just a plain red plastic jewel. I had a G.E radio/phono combination unit from the early 40s and it had a similar sort of lens mounted in the skirt bellow the speaker grille, it was kind of necessary since the control panel was hidden behind a door.
