I have some cases that are for Gillette Super Speeds from the 1950's. They all appear to be the same size and shape but they are different colors. Dark Red, Bright Red, Light Blue, Dark Blue and Tan.
I do know the Dark Red is for the Red Tip Heavy; the Light Blue is for the Blue Tip Light. But are the other three all for the Flair Tip Super Speed? Were the colors for different years or what?
