Design of Lodge Aero A-40, A-30, and A-20 spark plugs is discussed; early design of mica-insulated spark plug; used for high-compression engines. Model A-30 has patented heat-conducting copper sleeve between mica and steelalloy center pin; making plug for Rolls-Royce F type engine that will withstand great heat; A-20 used for engines of medium compression.
