In 20s, Ahrens-Fox`s bread and butter products was still the distinctive front-mounted piston pumper. But in 1928 the company introduced a companion line of 500, 600 and 800 gpm pumpers equipped with midship-mounted rotary gear pumps.

In this model designation, G indicates Gear pump, N is for Ahrens-Fox Model N (5-1/2″ x 7”) T-head motor, 80 stands for 800 GPM pump capacity, and 4 indicates it is equipped with a booster tank.
