The Beta range of commercials was introduced in November 1933 as an updated version of the Atlas but both models were offered until the Atlas was withdrawn in 1936. Both two axle (six ton) and three axle (eight to twelve ton) types were made.
At first the VR4 diesel was used but after the Atlas went out of production the VR6 became an option.
Chassis numbers were in the 951xx range.
The number made is not known and there are no known survivors.
