| SECRET. 4328 To HY.{Tom Haldenby - Plant Engineer} Copy to E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} DE. RHO. HDY.{William Hardy}1/MN.3/4/35. SPECTRECodename for Phantom III GEARBOX. With reference to the hole in the web of the frame for the arm of the gearbox it appears from an inspection of the frame for SpectreCodename for Phantom III 3 that the elongated hole originally provided for the accomodation of either the J3 or the SpectreCodename for Phantom III box as shown by N.Sch.4071 is still retained. If this is so will you kindly modify the instructions in accordance with N.Sch.4373 which shows the shape required with the more flexible mounting. Earlier drawings which show a reduced size of hole are N.Sch.4020 and N.Sch.4090, but these are now superseded by N.Sch.4373. HDY.{William Hardy} | ||
