Hs {Lord Ernest Hives - Chair} 2/LG12.1.22. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. VACUUM TANK. X3595 We are sending to you a model of the R-R Vacuum Tank made for Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. We suggest that you will most probably wish to make this tank of lighter construction. It appears to us to be unnecessarily heavy. We should like to have your comments as soon as possible.
