The Dennis N-Type is a model of commercial vehicle introduced by Dennis Brothers of Guildford (later Dennis Specialist Vehicles) in around 1905. It was the basis for their early fire engines and trucks
The "N-Type" chassis was constructed from rolled steel channel; riveted and braced at appropriate points. It incorporated a sub frame on which the engine and gearbox were mounted.
The majority of Dennis commercial vehicles were built on this type of chassis until further chassis designs were introduced. The last vehicles based on this design were produced in the late 1920s.
The chassis was generally fitted with engines by White and Poppe of Coventry. White and Poppe were bought by Dennis Brothers in 1919.
