One can't very well imagine that these propeller-driven contraptions would pass any inspection in today's health and safety-led culture, but back in the 1910s, when we expect these photographs were taken, things weren't quite so strict. Such machines would have been a dream come true for old Terry-Thomas. "I say, Courtney..."
What exactly are we beholding here? You may well have come across the propeller-driven Hélica by French engineer Marcel Leyat, one of which was restored in recent times and has since been attracting a lot of attention from visitors to motoring festivals. That, however, has its propeller mounted at the front, and it was encased within a cage to prevent it shredding everything which came too close. This one is mounted at the back with no protection whatsoever. "Courtney, be a good man and find out how to get that thing started, would you..."
The banked wooden track in the first photograph may indicate that car running on it was intended for record-breaking, but we haven’t been able to find any further information about it at all. The closest we could get was a vehicle named the Overland Wind Wagon (pictures two and three), which was made by the Overland Automobile Company and supposedly demonstrated at Indianapolis in June, 1910, at the Indianapolis Motor Speedway Aviation Show. Its eight-foot wooden propeller gave it a 53mph top speed.
That, however, is clearly a different car. Are we able to determine the base vehicle of our main monster with its big four-cylinder engine?

The mysterious car in the first picture stands on a board track. Racing motorcycles and cars on wooden board tracks was common in the 1910s and 1920s in the Unites States. The first board track for motor racing was the Los Angeles Motordrome, built in 1910.
The chassis is rather wide and comparatively strong, compared to the Ford Model T and similar cars of that era. Next to the driver a drum shaped object could be the tank. The car seems to have a single brake drum attached to the differential. Spoked wheels were quite common on runabout cars of the early 20th century and probably readily available. The front axle appears to be unsprung, while the rear axle could have a transversely mounted semi-elliptical spring.
The engine is a mystery by itself. I go along with Peter that it could be an aero engine. My best guess is an early water-cooled vertical four-cylinder two-stroke engine built by the Roberts Motor Manufacturing Company of Sandusky, Ohio, USA, during 1911 – 1912. A later version could be possible, too, as Edmund Willson Roberts (1866 – 1947) designed a total of 131 engines in his lifetime. Sadly I have not found an image to prove my idea.
