Dear Sirs,

re 3.5" diam. Piston RR.786.

We apologise for not having replied to your letter ref. WFR/SKW. dated May 1st.

We are reviewing the position of lighter chassis pistons, but our testing ability at the present time is very nearly reduced to zero.

We have however, checked over our figures, and the expected saving in weight for your latest cast of RR.786 should read 19.25 ozs. instead of 18.25 ozs. as previously stated.

We apologise for the error, and enclose our method of arriving at our conclusions, and when you have pursued this, we would appreciate your comments.

Yours faithfully,

C. F.{Mr Friese} Salt.
for ROLL-ROYCE LTD.
