You've likely heard the phrase, 'Now that's the real McCoy'.  Did you know that the phrase was birthed from an invention by Elijah McCoy who developed a lubricating cup that automatically and evenly distributed oil over the locomotives for steam engine moving parts while in motion?  While others put forth similar devices, railroaders often requested 'the Real McCoy'.  Patented in 1872, Elijah's invention was used on almost all railroads in North America by 1900.  

 

Of course, Elijah held over 57 other patents (including the lawn sprinkler), but sold the rights to some of his patents to raise money to open the Elijah McCoy manufacturing company

 

So, when ever you want an ACTUAL item v an imitation, be sure to ask for 'the Real McCoy' - an attribution to a master engineer.

I knew this, but good share
