This from Drew Smith:

Assuming this photo was taken in 1946: Pumper on the left is thought to be a 1926 purchased used in 1945. The original firehouse was built by volunteers in 1948 and in 1948 took delivery of a Ford/Darley which isn’t in the photo. Prior to having a firehouse, the rigs were stored in or behind a gas station (now gone – burned down in late 1970s) at the northwest corner of Elmhurst Rd (IL route 83) and Camp McDonald Road.
