(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} | ||
