Complete Spark Plug Display.
This display board was lent to us by Toledo who prepared it for their "open house" held June 7-8, 1947. This display board was placed in Department #35 Process Laboratory, just west of the elevator, and attracted considerable interest and attention as it showed the end use of the insulators.
