Truck Information:
This 1963 Mack is one of 137,000 B-model Mack trucks that were made between 1953 and 1966. Modern and aerodynamic in appearance, the B-series was developed in the late 1940s as the successor to the L-series, which was made from 1940 to 1956. The B-series was then replaced by the R-series, which was made for 40 years until it was discontinued in 2002 and replaced by the D-series. Some B-series Macks had five-speed transmissions, which was only possible because Mack engines have a wide RPM operating range. The radiator on this one is a hard nose, a cast radiator; you could get them with sheet metal radiators if desired. Mack would always build whatever you wanted; they were and still are a custom manufacturer. The engine, transmission, and rear axle were all made by Mack. They were one of a few manufacturers to make all of their own parts. If, however, you wanted another brand of engine or transmission, they would put it in for you. The B-series was made into a variety of configurations; in addition to heavy trucks, there were fire trucks and school buses. These trucks were extremely durable and serviceable, and well regarded by truck buyers and operators. This particular B61 was purchase new in 1963 by Oil Transport, Inc. in Waterbury, Connecticut. The tractor, along with the company, was later sold to R.J. Guerrera, Inc. who in turn sold the tractor locally. In 1985, Dick Guerrera purchased and restored the truck. In 1992, this truck made its debut at an American Truck Historical Society (ATHS) chapter show in Greensboro, NC, where it took home both the People's Choice and Exhibitor's Choice trophies. Iowa 80 Trucking Museum acquired the truck in 2011. Top Speed: 60 MPH
