It is understood that the SS.{S. Smith} will be continuing its trials in France, as naturally it will go through another 10,000 miles when the improvements are completed, such as :

(1) Engine mounting.
(2) Engine oil retaining.
(3) Exhaust system.
(4) Dynamo and starter small modifications.

G.4. with all its final parts will go through at the same time. They are in addition to the three items already agreed upon :

(1) Lower and longer frame with cross.
(2) Aluminium head with all its improvements in induction and exhaust.
(3) Four engine feet and rubber mounting.

R.{Sir Henry Royce}
