wiring for an old fluorescent desk lamp

I am attempting to rewire an old desk lamp that had the base detached to repair the desk attaching clamp. Unfortunately I did not label the wires in the base when I started this project several years ago. I am now attempting to rectify my mistake.
The base has two small transformers (ballast) with a single red wire running into the first then out to the second. The second has a single red wire out and single blue wire attached at the red inlet connection.
Now it really gets messy, the wiring coming from the lamps, which are intact and I believe a preheat type with a 3 position manual starter switch. There is a single white, green (not a ground) and black wire going to the bulb wiring and switch.
The normal plug input wire has a black, white and green wire. I know the green here is a ground.
Any help here would be greatly appreciated. All the diagrams I can find do not mention a 3 wire ballast.
