This was the first "modern" US pumper, with forward control and canopy cab: it was introduced in 1947 - although the open cab JOX ladder chassis with a similar configuration appeared a few years earlier.
This configuration basically did not change for another thirty years, until four-door cabs were finally the standard, and the ALF layout was copied by all of the other custom fire engine builders, including Pierce, Pirsch, Ward La France, Seagrave, E-One, Mack, and many others.
The engine was behind the front seat, with two rear-facing "jump seats" either side, facing backwards under the canopy. These were very narrow, and often ignored by crew members, who preferred to ride the rear step!
