| X4094 342 To RHC.{R. H. Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/Les.25/KW. 19.9.34. SPECTRECodename for Phantom III SHOCK DAMPERS. Will you please modify the centre tubes in the front shock dampers to Hs.{Lord Ernest Hives - Chair}1519. We shall need another standard pair in case the experiment is unsuccessful. This is a method to obtain a variable leak damper, so that the large leak in the centre position diminishes when the wheel gets near the buffers. Hs{Lord Ernest Hives - Chair}/Les.{Ivan A.
