4-Speed with Chain Drive

Truck Information:
This Mack AC was the last of three delivered to The U.S. Trucking Corporation of New York City by the Mack Queens Branch on November 10, 1937. This truck was originally equipped with a Heil Box and has a reproduction of that box at present. There is record of only two more 4-cylinder ACs made after this one. This model has a single drive axle, chain drive, and narrow width axles. The engine in this truck was specific to Mack ACs, the 4-cylinder block design was introduced in 1928 and used until production ceased December 10, 1937. There were 40,299 ACs produced from 1915 to 1938, making it the longest production run of any commercial vehicle in American History. It was this model that gave Mack its famous Bulldog Trademark. This specific truck was previously owned by Francis Ryan from Chelsea, Vermont. Mr. Ryan owned his own heavy haul business under the name F. Ryan. He was a truck collector far before anyone knew they would be valuable as antiques. Through the years he owned several hundred antique trucks. This truck has been part of the Iowa 80 Collection since 1980 but was newly restored in 2011. Top Speed: 20 MPH
