Patrick, schematic showing 2 light bulbs is probably a typo, as this particular model didn't have a shadow meter, so more than likely it only had one dial lamp and that was it. 

If my model 116B is of any guide as far as how the pilot lamps are wired up in it, the way yours should be wired up is that it has the hot side (the wire that's still there in your radio) wired up to the center contact of the bayonet socket and the outer contact was wired to chassis ground via a screw terminal.
