PISTON MODS. TO PREVENT SEIZURE.

From our results we recommend that pistons to ECD.911 are fitted to Sg.{Arthur F. Sidgreaves - MD} Hs.{Lord Ernest Hives - Chair} and Mx{John H Maddocks - Chief Proving Officer}'s car as soon as they are available, and they can be standardised when any one car has completed the requisite mileage.

Personally we should like to get 15,000 before they reach customers' hands.
