Cummins also supplies engines for Dennis buses. In fact, the
Leyland Lynx and Leyland Olympian 3-axles also use Cummins
engines.
A check at the Cummins webbie says they have the C245 (Dennis
Lance) engine in their product range. So which one does the Sabre
fire truck use? If I'm not wrong, there is also a model called the
Rapier.
Dennis is part of the Transbus grouping, which also includes
bodywork specialist Walter Alexander.
