| To RHC.{R. H. Coverley - Production Engineer} from E/JNK. c. Hs.{Lord Ernest Hives - Chair} E/JNK.5/HP.7.7.33. 17060 Phantom 2 Automatic Tappets. We send you herewith: LeC.3564 showing a new design for the plunger in the valve rocker. We have altered this from the previous drawing because of more knowledge on the subject in regard to air trapping. If the plungers are partially made to the original design we think the best thing to do is to scrap them. The rockers will be O.K. E/JNK. | ||
