| PYRAMID Starting and Lighting Brushes Pyramid Brushes reduce starting and lighting troubles to a minimum because they are made and designed for the particular service to which they are appplied. The great advantage of the Pyramid Brand Brushes lies in the fact that these brushes are made to fit any and all of the starting and lighting systems now on the market. This enables any electrical dealer, garage man or service station man having a stock of Pyramid Brushes to make replacements on any make or model of car. Pyramid replacement brushes can be recognized by the three pyramid trade-mark which is stamped on every brush wherever mechanically possible. In addition to the trade-mark each brush is stamped with its code number. This avoids the possibility of the brushes becoming mixed in stock and at the same time offers a sure means of identification. Pyramid Brushes are sold in assortments to meet the needs of any dealer—from the small garageman to the largest accessory dealer. National Carbon Company, Inc.
