There are six known surviving 12hp R&V engines. Five are "Triumph Line" engines (four 'L' line and one 'R' line engine) and one sideshaft engine. My engine is now fully restored and will be attending a number of rallies this year. It is a very smooth running engine and is very reliable.
Some 12hp 'L' Line specifications: RPM:325; Flywheels: 40 inches diameter, weight 385 pounds (143.6kg) each; Piston rings: 5; total shipping weight: 2300 pounds (858.5kg).
NEWS: GL46667 finally returned to life at 8pm on Thursday 6th September 2001. It started fairly easily (after about 10 turns) picked up speed, and governed perfectly. It ran for about 20 minutes in total (after a couple of stops to check things). There are no unusual knocks or noises and it runs very smoothly.
This 12hp Triumph (GL34036) belongs to David Miller in the USA. This
is a straight petrol engine and also has the Wizard magneto mounted on the
ignitor. Note it has a square pushrod to allow for the Wizard.
This is an impressive way to carry a 12hp R&V
David Miller's after restoration (2002).
