The Triumph Model N Deluxe was introduced for 1929 and was an upgrade from the 1927-28 Model N with a new saddle style petrol tank. It still had a total loss oiling system, but this was to be its last year as Triumph was introducing its new models for 1930 with a full recirculating system. So given that the N Deluxe was only made for one year this instruction manual must be a god send for an owner who wants to know the specifics, including maintenance, about their machine. Usual chapters on lubrication, maintenance, engine and gearbox dismantling are included as well as fault finding.
