Truck Information:
This 1915 Mack AB happens to be the oldest AB that's known to exist. It was a very popular truck; in fact, the AB model was Mack's first standardized high volume truck model. Mack has good records on every single truck that they built. This is serial number 361; it's the earliest one that they've ever had an inquiry on. It was a great truck in the right size and at the right price. From the beginning, Mack Trucks were known for durability. This model was made from 1914 to 1937, and the design remained relatively unchanged. They were made in 1.5-ton, 2-ton, and 2.5-ton capacity ratings. There were 383 AB models built in 1915, and 51,364 built during the full span of production. Mack ABs were made in either worm drive or chain drive. Gear ratios available at the time were from 5.75 to 1 all the way to 10.5 to 1. Depending on the gear ratio, the truck had a top speed of 13 to 25 miles per hour. That may not be faster than a horse, but a horse could only go so long before having to rest; you might have to change horses in the middle of the day. The truck on the other hand would just keep going hour after hour. The Mack Brothers Company was founded in Brooklyn, New York, by John and Gus Mack. There were five Mack brothers who were associated with auto and truck manufacturing in the earliest years. Early trucks were built in Allentown, PA. By the mid-1920s, the company had been sold and the Mack brothers were no longer involved. Top Speed: 24 MPH
