| PER BAG. 1114. W/S. Bkl. from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} Rm{William Robotham - Chief Engineer}/Gry{Shadwell Grylls}1/R.14.1.37. We are sorry that your memo Bk{A. Birkett - Commercial Manager}1.11/4.1.37. has been mislaid. We do not quite know for what reasons Mr. Bourdon wants the information, but there does not seem any harm in telling him that the "oil temperature regulator" is merely an oil cooler. This cooler is of the matrix type, and makes the water in the cooling system lower the temperature of the oil.
