| To Hs. {Lord Ernest Hives - Chair} from R. {Sir Henry Royce} X5970 R1/M26.6.25. X.4425 X.8970 X.5970 Would you please send to WW. 2 doz. of the latest porcelain cleanable plugs - for New Phantom(Codename for PHANTOM I) and Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)). The doz. we have here are the old-fashioned Lodge mica plugs. If you find the cleanable ones unsuitable for the New Phantom(Codename for PHANTOM I) or Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)), send those with porcelain insulation as at present on the New Phantom(Codename for PHANTOM I). This type of plug is just possibly cleanable without detaching it. R. {Sir Henry Royce} SEE ORIGINAL FOR SKETCH. | ||
