There is not much information out there on the Burd Piston Ring Company. Most references have to do with Burd being the primary sponsor on the car of the 1938 Indianapolis 500 winner, Floyd Roberts. This advertisement comes at the end of the same year when The Gabriel Company (of shock absorber fame) bought the company. After that, Burd seems to have just slipped out of America’s consciousness over the next decade or two. The history section of Gabriel’s website doesn’t even mention them.
