VISUAL DESCRIPTION
This vintage advertisement showcases "The Rocking Horse," a device used by the Boffins in the Cellon Research Laboratory to test the hardness of Cellon Finishes. The image depicts an intriguing mechanical instrument consisting of two hoops and a pendulum, designed to simulate wear on aircraft finishes. When placed on a test sample and set into motion, the rocking horse mechanism will come to rest sooner on glass than it would on harder surfaces. The number of 'rocks' is then measured against a calibrated scale, providing an accurate assessment of durability. This ad emphasizes Cellon's commitment to maintaining high standards in appearance and wearing qualities for their aircraft finishes.
