1922 Bugatti type 23 Brescia

raced in 19 of 23 Indy races, more than any other racecar, and once owned by Charles Bronson, this Harry MIller and Earl Cooper 1927 racer has pedigree and history

1923 Avoin Voisin factory research race car, the C6 Laboratoire, simply a most amazing innovative and obscure try at a racecar from airplane engineers

 Quite odd looking, maybe the strangest I can recall ever seeing

 Why it has a prop on the nose, I'd only guess that it's for airspeed. Boardtrackfan commented that he thinks its for a water pump

 and I was astonished to see it has the actual "Windscreen" that I've only heard of but never seen before

Click on the above gauges and get a good look at the full size... those are pretty unusual

 and a square-ish steering wheel... boardtrackfan reminded me that this isn't so uncommon, it's so the driver has a better view when driving straight, and more legroom

  here is the big indication of the aeroplane style engineering they brought to their race car... cable brakes. But not connected to the brake pedal, this is independant front and back brakes for a racing advantage

1955 Ferrari 750 Monza Scaglietti Spider, one of 35 built, race winning in Phil Hill's masterful hands, and starred with Fred Astaire driving it in a Gregory Peck movie
