Ballot

The Ballot 3/8 LC was developed following World War 1 in France. It competed in the 1919 Indianapolis 500 as well as a number of Grand Prix races after that. It was designed by Ernest Henry. It was powered by a 3 liter 8 cylinder engine with dual overhead camshafts. It had four valves per cylinder. It was a very technically advanced engine for its time. It had limited racing victories but was an important step in the evolution of racing engines at the time. 

Hispano-Suiza "Black Bess"

 

The name Black Bess has been associated with several different racing cars and the story is a bit confusing. The information I found was on a Spanish language site. Google translate will render that in a language of your choice. Have a look at La Escuderia.
