LARGEST GIRCULATIO

This is the finish SAYS THE BOFFIN

One of the many safety features of the Lockheed system is its freedom from parts likely to bind or suffer from friction trouble. All wheel brake cylinders, for example, are super-finished by the thearingising ' process, which consists of plgnishing the cylinder walls with high-speed steel rollers to a degree of smoothness so fine it can only be expressed in micro-inches. This not only ensures a perfect hydraulic seal between cylinder and piston, but virtually eliminates friction and prolongs indefinitely the life of the rubber cylinder cup.
