The 1903 De La Vergne is rated at 125 HP. It was on exhibit at the 1904 World's Fair in St. Louis. It was then installed in the W.F. Norman Sheet Metal Works in Nevada, MO. There, it was belted to a line shaft and powered sheet metal forming machines for about 50 years. The engine arrived at Rollag in 1976, owned by the Withers family and operated by Tom Michalson.

It has a 26" bore (3" bigger than a 55 gallon barrel) and a 38" stroke. Its two identical flywheels are over 9 feet in diameter and 12.5" wide. The two flywheels and the crankshaft have a combined weight of 15 tons. The base and cylinder weigh 20 tons more. Each main bearing cap weighs 700 pounds. The total weight is 40 tons.

It is believed to be the largest single cylinder, open crankcase, four cycle, internal combustion engine running in the world!
