Bowen} 1028 Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}2/AP.23.11.37. BRAKE DRUMS WITH CAST-IN END PLATES. We are sending you a set of drawings EX.S.142/3, 144/5 shewing Ph.III. brake drums with cast in end plates. May we have a comparative price between these and the standard system, both made in our Foundry. If the saving is a useful amount we will make and test some drums of this sort, but if it is small we shall not do so. Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale} | ||
