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 February 1916,  is  utterly reliable, full of character  and a pleasure to ride; what more can you want from a vintage machine?
