As I suggested, look at the diagram.

You will see that the pin 5 is a dummy pin.
They use it as a solder post, just to hold a wire. It is a popular practice.
Pin 3 is one end of the resistor which is consistent with how it should be. Now the pin 7 then (another end) should go to the strung up filaments, and also to the dial lamp.
Pin 8 should also then go to the dial lamp.
