From the Rolls-Royce experimental archive: a quarter of a million communications from Rolls-Royce, 1906 to 1960's. Documents from the Sir Henry Royce Memorial Foundation (SHRMF).
Clarifying the success of E.4237 cast iron pistons is due to the omission of the E.3028 stiffening plate.

Bentley / Mr Barrington} c. to DA.{Bernard Day - Chassis Design} c. to F.{Mr Friese} X 3754 chassis EP{G. Eric Platford - Chief Quality Engineer}3/F2.1.20. RE. CAST IRON PISTONS. With reference to your Hs{Lord Ernest Hives - Chair}3/LG31.12.19, I trust it is realised that in pointing out that E.4237 pistons have been the most successful, this has only been achieved by leaving out the stiffening plate No. E.3028.
