El Pampero, built by Barron Lee Ackroyd in 1912
That is correct! J. Barron Ackroyd (that's how his name appears in the RAF registry) was a British Royal Air Force pilot who designed and built this cyclecar with a 2-cylinder, 12 HP engine, and named it "El Pampero" to evoke Argentina, a fashionable and exotic location at the time. Ackroyd was killed five years later during WWI, in combat against "The Flying Circus", the Red Baron's unit. The car now belongs to Portuguese collector João Manuel Magalhaes, and is on display at the Auto Museum of Málaga, Spain, where I took the photo.
