| 312 To HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Smth. Rm{William Robotham - Chief Engineer}/Smth.6/BJ.23.4.37. Phantom III Clutch Plates - Long Type. Will you please note that during the development of this plate we have made one or two modifications to the pieces, all of which are indicated on the arrangement Ex.27309. Unless otherwise stated, therefore, the plates now going through the shop and any future plates, should be made to this arrangement. We are not sure how many plates have been instructed, but we want to bring the total up to six, and should be glad if you will arrange accordingly. We have ordered the facings, and the spring plates Ex.23084/A.{Mr Adams} are due from Borg and Beck's in about 10 days time. The modifications to the facings, rivets and centre plate indicated on Ex.27309 also apply to the disc which you are preparing for the new clutch N.Sch.4998.
