Hs{Lord Ernest Hives - Chair}/GWH.{George W. Hancock - Head Chateauroux} PHANTOM EXHAUST CUT-OUT. X7490 -------------------------------- Referring to Dal/M.15.1.27. the improved silencer operating scheme referred to in your memo above, design N.Scheme 2216, has been instructed and tried out by the Experimental Dept. and is actually on order for D.2.

We are bringing the scheme referred to in Mr.Hancock's memo Hs{Lord Ernest Hives - Chair}/GWH{George W. Hancock - Head Chateauroux}1/LG.13.1.27, in for C.2. Series. 1804 BY.{R.W.
