Briggs Cunningham built his C-4RK with a B17 24 clock, which incre4ased the difficulty of making a recreation, a perfect recreation

The 24-hour clock on the original’s dashboard was from a B-17 bomber.

After six years of work, it was completed just in time for the Cunningham reunion at the 2018 Greenwich Concours. 

Every component has a story. The Marchal driving lights required a trip to the Retromobile show in Paris, as Schoendorf couldn’t find the correct units in the U.S. Most Marchal lights in the States have a small nipple in the middle; the C-4RK had units with a small crease running lengthwise. The 24-hour B-17 clock was found on eBay, also difficult to find, but not impossible, were the Halibrand magnesium wheels, the Pontiac taillamps, Stewart Warner gauges, Renault 4CV license-plate light.
