Mack Trucks Historical Museum What year did the Mack Senior model debut? When was the first Mack diesel engine produced? When did Mack adopt a bulldog as its mascot? Or a little closer to home: What transmission was outfitted on your grandfather’s 1940 Mack? If you’ve got questions — and perhaps a vehicle identification number — there’s a pretty good chance the Mack Trucks Historical Museum has the answer in their archives. In addition to being the authority on all things Mack, the Mack Trucks Historial Museum also restores and preserves vintage Mack trucks and memorabilia for all to enjoy.
