Chicago FD Turret Wagon History (pt 18)
Another installment in the history of turret wagons within the Chicago Fire Department, brought to you by Jack Connors. The images showcase "Big Mo," a notable unit that saw two different chassis throughout its service life. Initially assigned as 6-7-2 on a 1953 International 6×6 chassis, it was painted in a striking black-over-red scheme. This version carried shop number G-248. Later, it was reconfigured onto a 1957 GMC 6×6 chassis, now painted in the blue and white colors associated with Civil Defense, and was assigned shop number G-157.
The photos featured here come from Jack Connors’ collection, along with contributions from Ken Little and George Brown. These images offer a rare glimpse into the history and operations of one of the department’s most recognizable vehicles.
