1921 Dennis N FA1075, Brighton 2000. (Barry Hutchinson)br/br/emGordon McLaughlin writes/em ...br/A photograph of FA1075 appeared in Keith Jenkinson's book Preserved Lorries published in 1977. It is in the same condition as in the Brighton photograph with pneumatic tyres and a short ladder. The book describes it as a Dennis S Type and says that it then belonged to Mr Osborne of Saffron Walden. The description of the vehicle is very similar to that given in a separate entry for the N Type which it says was discontinued in 1919. br/br/I can't see much difference between the two machines and can't claim to know much about fire engines. Had Jenkinson got the model identification wrong? I notice that the Dennis brochures reproduced on line don't mention model letters and tend to refer to technical features to identify different types. I'd be really grateful if you could help with identification of these early machines.br/br/emBarry Hutchinson writes/em ... br/You are absolutely right Gordon. Dennis specified all their early Fire Engines up to the mid 20's in terms of engine HP ratings. From then onwards it was primarily in terms of pump rating (such as a '250 gallon model') before switching to the more evocative names in the mid 30's such as Big Six, Light Six, Big Four and Light Four.br/ br/I have to disagree with the nomenclature 'S' Type. The 'Preserved Vehicle' book is the only mention that I have ever seen of an 'S' Type. FA1075 built in 1921 only differs in only the smallest of details from machines which were built from the start of the first war. br/ br/The 'N' Type designation was used by Dennis internally during this period, with perhaps 'N' standing for 'Normal'. Most people would consider that the switch from the big Gwynne fire fighting pump to the smaller Dennis/Tamnni pump was the end point of 'N' Type production. Another distinguishing feature at this time was a change from a separate PTO for the pump to a combination PTO with the gearbox.br/ br/I purchased FA1075 from Tony Osborne 15 years ago. Since then 3 more 'N' Types have joined the collection. If you really wish to be bored www.dennisfire.co.uk shows them all, including FA4067 which is the last evolution of the 'N' Type line with the 60HP White and Poppe engine.
