Before Graham-Paige was consolidated as a company, Graham Brothers was introduced in 1921. This was a commercial vehicle brand that primarily manufactured trucks and pickups. Graham Brothers vehicles included 1 and 2 ton models, with four and six inline cylinder engines. These trucks were offered with 4-speed manual transmissions and rear-wheel drive, and were known for their ruggedness, being used both in commercial transport and as emergency vehicles such as fire trucks. Graham Brothers vehicles were produced until 1928.
