The company name is Johnson Propeller, but it seems that many people call it OJ Props. How did that come about?

We were founded in Oakland in 1936 by my great grandfather Oscar and his son Ivar. In the early years, we used to stamp the propeller on the side with Oakland, Calif. USA, so people started referring to Johnson Propeller as Oakland Johnson, and it morphed into an homage to Oscar as OJ.
