Spitfire Headlight Springs

[tullybrewing]

According to the parts manual, the # of headlight springs required is 4. There are only 3 screws that hold the headlight assembly to the cowl. Can anyone go take a look at their Spitfire and see if perhaps one of the screws is supposed to have 2 springs on it, while the other two have 1 spring on it? I took mine apart and didn't pay attention, as I do have 4 springs and not sure which of the screws are supposed to have 2 springs on it.
