His first motorized ladder truck was on a Rambler chassis, and this was followed by others based on Couple Gear, White, Duplex, Nash and Dodge.

In 1938 came the first 100 ft aluminum alloy closed lattice aerial ladder which became a Peter Pirsch specialty and is still used today.

Conventionals and cab-forwards were made through the 1960s with little change, and Pirsch were also offering their specialties on other chassis such as Ford and Mack CF.

Very few conventionals were made after 1970, and current production centers on rigid and articulated cab-forward units, mostly with diesel engines.

[6] Pirsch and Sons supplied many of the fire trucks sold throughout the State of Georgia from 1950 until 1980, with their first regional distributor being the Harold Hancock Company of Atlanta, followed by the Charles L. McLarty Company of Decatur, GA. Atlanta Georgia, and surrounding cities and towns bought dozens of Pirsch trucks supplied by these two local businesses.
