After building one truck and one automobile in his wagon works in 1907, W.G. Hahn decided to build trucks as well as wagons. Truck production was minimal prior to 1913. Hahn built conventional chain drive trucks powered by the Continental 4-cylinder engine. The 1 ½ -ton chassis cost $2,400 in 1914.

Five models from 1500-pound to 3Yo-ton capacity were built from 1915, when Hahn also began building fire apparatus. A 5-ton model filled out the line in 1918. Hahn used worm drive from 1916, although the first 5-ton trucks had chain drive. Postwar inflation resulted in a chassis price of $10,000 for the 5-ton truck in 1920.

In 1922 Hahn offered eight models from 1-ton to 6-ton with prices from $1,750 to $4,650. Production in the 1920's averaged 600 trucks per year until 1927 and in­creased thereafter. Hercules engines were used from 1923. When the first 6-cylinder models were introduced in 1926.

Continental and Hercules engines were used in both the 4­cylinder and 6-cylinder lines. Hahn offered 27 and 35­passenger bus chassis with the 6-cylinder Continental engine and a 20-passenger bus chassis with the 4-cylinder Hercules engine.

Hahn took over the former Bethlehem plant in Allen­town in 1927 and moved their offices there, although the Hamburg plant was continued. A line of trucks with the 6­cylinder Continental engine was announced in August, 1929. Seven models priced from $1,098 for the ¾ -ton to $4,950 for the 5-ton were offered. All models featured 4­-wheel hydraulic brakes and a distinctive cast aluminum C radiator shell. A merger with Selden lasted 16 months, during which time some Hahn models were offered under both name plates.

Hahn returned to Hamburg in 1931 and retrenched in their own factory. Some trucks built in the early 1930's were powered by the 4Y2-litre Franklin 6-cylinder engine. Hahn concentrated on fire apparatus from 1933, although a complete line of trucks powered by the Waukesha 6­cylinder engine was offered on special order until 1941.

During World War II, Hahn manufactured mobile machine shops and special recovery trucks for the U.S. Engineer Corps. Hahn's only post-war truck production consisted of a large order of delivery trucks built on Ford chassis for United Parcel Service. Since 1948 the firm has limited manufacture to a line of custom fire apparatus.

Since the 1950's the forward control cab has been used to increase chassis space for the many new pieces of fire fighting equipment. Chassis and body are of Hahn manufacture; engines used are either Detroit Diesel or Wau­kesha gasoline. Production in the early 1970's has aver­aged 100 custom fire engines a year.
