This project of a Mr. J.H. Norris appeared at Donington in 1938 and apparently created a great deal of interest. Based on a longstroke Sunbeam sidevalve the supercharger was "built from scrap" and takes its drive from the primary drive at the clutch. No information on the meaning of "NS" on the tank and sadly, no information on how well it worked.
Published by the A.L. Burt Company (New York) in 1905, it's interesting to see the automobile beginning to gain enough acceptance to be the subject of a novel. It was co-written by the British novelist Alice Muriel Williamson and her husband Charles Norris Williamson. They jointly authored a number of novels, many about the early days of motoring.

Fifi, the Superfortress belonging to the Commemorative Air Force paid us a visit at the Hamilton airshow last weekend. Out of 3970 B-29s built, and 22 in museums it's the only flying example. An imposing machine, to say the least.
"The hero's white car, named the "Leslie Special" was specially built by Warner Brothers to resemble a Thomas Flyer, the car that won the 1908 New York to Paris Race. According to the Petersen Automotive Museum, four "Leslie Specials" were built. One of the four appears painted green in the 1970 Warner Brothers film The Ballad of Cable Hogue—the grille can be seen bearing the words "Leslie Special". Another of the four is at the Tupelo Automobile Museum listed as a 1963 Leslie Special Convertible.
The villain's black car was named the "Hannibal Twin-8"; five were
constructed. One of them is on display at the Petersen Automobile
Museum, powered by a Volkswagen industrial engine. Another is at the Volo Auto Museum
in Volo, Illinois. This model includes a prop "cannon" and a working
smoke generator. The Volo museum describes the Hannibal Twin-8 as built
by Warner Brothers at a cost of $150,000, powered by a Corvair
six-cylinder engine with three-speed manual transmission and six wheels.
All four rear wheels are powered by a chain drive."
