| W/P. Sr/Crn. from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} 124-5 Rm{William Robotham - Chief Engineer}/Gry{Shadwell Grylls}4/R.26.4.37. We have read with much amusement R.{Sir Henry Royce} Giraud's letter. As he has not patented his invention, and we do not wish to get entangled by guarantees of secrecy, we think we had better let the matter drop and let some other manufacturer try the device first.
