Will By.{R.W.

We will write to By.{R.W.

Will By.{R.W. Bailey - Chief Engineer} kindly arrange to send us particulars (composition) of the crankshaft steel which can be given to Messrs. AUBERT & DUVAL when we send them the crankshaft for re-nitriding. We should like similar information to that contained in Rm{William Robotham - Chief Engineer}/Swdl.{Len H.
