let me be your ruler

These vintage yardsticks were a multitasking tool. They were also real estate for advertising, and were give-a-ways to mechanics who would utilize the numbered holes to keep valves in order during a valve job. Each valve would create a specific wear pattern, so keeping track of which cylinder it came from was important for future optimal performance of the engine.

Engines have greatly improved since the 1950’s, when every 20,000 miles you would have to visit your mechanic for valve maintenance. With improved materials and better oils, the valve job and the yardstick valve holder have become things of the past.
