| 628 x4709 KGR4 To Dr. from HDY.{William Hardy} HDY.{William Hardy}3/HP.5.10.34. c. Hs{Lord Ernest Hives - Chair} HHG Wraith Gearbox. -------------- We find that as drawn on N. Sch.4161 the slots milled in the S.M. sleeve for the extensions on the actuating collar coincide with the tracks of two of the spring plungers. To obviate this we suggest a rotation of the cam pins relative to the split in the collar as shewn on N. Sch.4217 herewith. HDY.{William Hardy} | ||
