Dear Sirs:

We have your letter of the 9th March, reference RM{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}9/AP., regarding the viscosities of recommended oils.

It has been suggested to our Sales Department that the S.A.E. viscosity numbers of our standard grades should be indicated on the packages, and we shall have pleasure in writing you further regarding the decision taken.

Yours faithfully,
FOR ALEXANDER DUCKHAM & CO. LTD.
