Looks like a Prospect triple combination pumper from the 1920's. It is hard to tell if it is a tall or short radiator, but is has a below the axle wishbone.

A "Utica" brand fire truck built by the O.J. Childs Company in Utica, New York.
Looks like Keith and I posted at the same time. Keith, while I would agree that the Prospects looked similar, if you look closely at the logo on the side of the fuel tank behind the seat, you can just make out "Utica". This photo is also on page 98 of Matt Lee's "A Pictorial History of the Fire Engine" Volume 2 "The Decade of the 1920's".
Keith, it has the narrow bottom piece on the radiator shell and lacks the lips on the front fenders. That would make it a low radiator in Aus.
