Triumph 1916 549 cc Model H frame # 275780 engine # 45432 OTP
The model H is announced late in 1914 as a logical development of the famous veteran “ Trusty”.
But it isn’t just a 1914 model with a countershaft gearbox: the engine differs from the veteran engine in various ways.
It has a single cam wheel with 2 cams instead of separate cam wheels for the inlet and exhaust valve.
The casting for the cylinder is entirely new, the valve head diameter is enlarged by ¼ inch and the valves are spaced further apart.
A great improvement over the 1914 style 3-speed hub is the Sturmey Archer countershaft gearbox. The primary chain drive is enclosed by a neat aluminium cover; secondary drive is by belt.
The model H becomes a very successful model: some 30,000 are supplied to the British and allied forces during the War; total production till 1923 amounts to a grand total of 57,000.
This matured and venerable H, assembled in September 1916, has seen service during the Great War and comes complete with French registration papers.
She has been touched up a long time ago, when, due to shortage of correct tyres the wheels have been fitted with smaller rims.
This machine is an excellent restoration project.
Although: much of the original enamel and nickel finish is still there, so a sympathetic restoration might do more justice to this Trusty mount.
