The 'Wolf' chassis, launched in 1933, became an extremely successful, long-lived design, appearing in many different forms thanks to the large variety of bodies that were fitted.

The chassis continued in production until the late 1950s.apart from a break during the war years. Over the years many improvements were made as technology changed. Later models included a version powered by a Perkins diesel engine.

The Guy 'Wolf' would have been a familiar sight in many countries thanks to the company's excellent reputation abroad, and the successful export department.
