The Redditch  based Royal Enfield firm entered the motorcycle business as early as 1898:  In the early days engines from De Dion powered their tricycles and quadricycles; Minerva supplied the power for the first motorized cycles. 
In the years before WW I  the company was very successful with light  Motosacoche-engined V twins. 
These machines were equipped with the famous Enfield two-speed gear, involving twin primary chains. In the rear wheel  hub a rubber cush drive was fitted, to take the punch out of the chaindrive. 
This  cush drive  was to be incorporated into all Royal Enfields until the very end. 
The 1939 range consisted of no less than 18 models, ranging from a 148cc  OHV  midget   to a 1140 cc V-twin  giant.  
The Model H  combination  was sold only as a complete outfit.  
Bore and stroke of the engine are 85 ½   x 99 ¼ mm . 
The machine has a four speed  gearbox with foot change and special sidecar ratios.
The handlebars are mounted in rubber and the front forks are made of pressed steel.  
Ignition is by  a Miller battery-coil system. 
The sidecar is equipped with front and side screens and has excellent luggage accommodation. 
This combination has been restored some time ago with great care.
