The #19 Ford Gaillion was built by Charles Montier, one of two Ford agents in Paris, France. The Gaillion name was chosen to honor a hill climb racing location where Montier often raced. This car raced in the very first 24 hours of Le Mans race in 1923 and finished in 14th place.
Montier used a standard Ford Model T 177 c.i. (slightly less than 3 liter) side valve engine; could possibly have been sleeved down to 2-liter (122 c.i.) displacement. He made the radiator taller than a standard T, with a larger capacity to aid cooling.
It had a standard planetary two-speed transmission augmented with a two-speed Ruckstell axle. Montier at some point replaced both with a French-built Synpar three-speed gearbox (which omitted the transmission brake as equipped by Ford.) He lowered the chassis by using a new fabricated wishbone at the front and a new crossmember at the rear, both created and patented by Montier.
He used Weymann-type fabric-covered four seat bodywork which complied with the new Le Mans race rule requiring all cars with engines over 1,000 cc to have four seats. The car also had two-wheel brakes (rear only), with new larger drums machined to run with friction linings.
After the 1923 Le Mans 24 hour race, Montier updated to four-wheel brakes
