Gillette Superspeed Set (Red, Flare and Blue Tip), 1955 (A4)
From 1955-60, Gillette sold three varieties of Superspeed. They called them Light, Regular and Heavy, but the Light and Heavy have become known by their paint job, as Blue Tips and Red Tips. Gillette advertised the Blue Tip as being for younger shavers and those with sensitive skin, and the Red Tip as "for men who like the heft and feel of a heavier razor." And it is in fact a bit heavier: 2.3 oz compared to a 2 oz. Regular and a 1.7 oz. Light. Red Tips have become a favorite of those who prefer a bit more aggressive shave, though they are still quite moderate compared an Old Type, for example, or many Single Edge razors.
These Superspeeds, one of each type, were all produced in the 4th quarter of 1955, the first year they were all available. They are functionally just fine, but do have some minor cosmetic issues: the Red Tip has some brassing, especially on the underside of the head, and the Flare Tip is missing one end cap. The blue and red paint is pretty much intact, though, aside from a few chips.
