Sub-Series I: Firefighting Apparatus

This sub-series of photographs features photos of firefighting apparatuses such as fire engines, hose wagons, steam pumps, fire trucks, and rescue vehicles. The separation of these materials from other photos was based on Thomas Mills III's study of these machines. On some photos in the collection, he would name everyone in the photo. Others, he would describe the apparatus, including the date in which it was ordered, the date in which it was shipped, the model and serial number, and which unit utilized it. If it was clear that the notation on the back was aimed at the apparatus, then it was placed in this sub-series.
