Saving the most impressive CFD turret wagon for last, this article showcases a series of detailed images captured by Jack Connors, offering a comprehensive view of 6-7-3—commonly known as Big John when it was new. These photos highlight every angle and key feature of this iconic piece of firefighting history.
Big John was one of the most powerful fire apparatuses ever built for the Chicago Fire Department. Its twin turrets were capable of delivering massive amounts of water at high pressure, making it ideal for tackling large-scale fires. The combination of advanced hydraulics, onboard pumps, and generators made it a formidable tool in the department's arsenal.
