| To D.{John DeLooze - Company Secretary} from E To CJ to CLK ORIGINAL x 1093 x-4260 GOSHAWK II FRONT DUMB IRON E3/5321 3. Referring to N.Scheme. 755. You refer to, on memo E1/G 27121 you will find that the item portion of the dumb iron fitting should be drop forged solid which will make the forging reasonably easy. Instead now, however, of roughing out with a large milling cutter as on E1/G27121 Mr Royce suggests removing the material by drilling with a flat ended drill to the arrangement shewn on the sketch previously to the profiling operation. Would you kindly instruct the Departments concerned. E [Stamp]: Hs{Lord Ernest Hives - Chair} MAR 7 1921 [Stamp]: RECEIVED | ||
