About this creation
For more than a century Mack has been among the leading builders of commercial trucks. Mack Trucks was active in the fire apparatus industry from 1901 to 1990. The firm was founded in Brooklyn, New York, in 1901. In 1905 the five Mack brothers moved their operations to Allentown, Pennsylvania.
The Mack AC was developed in 1915 and introduced in 1916. The Model AC featured a 74 hp four-cylinder gasoline engine with a three-speed transmission with a chain drive. Model AC trucks served in WWI and it was in Europe that they were dubbed "bulldogs" by the British. The nickname was based in part on their looks and in part upon their performance and reliability. The nickname stuck and the bulldog became the Mack logo.
Over 40,000 AC trucks were built between then and 1938. A significant number of these were built for the fire service through 1928. The exact number appears to be unclear. Mack offered 13 different types of fire apparatus on model AC truck chassis. These included chemical cars, hose cars, pumpers, city service ladder trucks, tractor-drawn aerials and squad cars.
Thanks for adding your MOCs to the group, glad to have you as a member! You may add some more MOCs, if you like, since cars and trucks until ~1940 are admitted (even if they aren't "vintage" in the strict sense of the word but rather "pre war"). But do as you please.
Your rigs are so consistently good. I love the fact that you do an amount of research far above the average builder. This is one of your best builds. The Mack is such an iconic piece of apparatus, and you've done an outstanding job capturing it. Keep these great rigs coming. Regards, Eric.
