| Lov.{Mr Lovesey} RHC.{R. H. Coverley - Production Engineer} X3067 EB/Thn6/T10.12.31. Re. CERRIC ENAMEL FOR AERO ENGINES. With reference to the visit of John Hall & Sons representative whom you brought to us a few weeks ago. The sample enamel has now arrived from these people, and as suggested at the time, we are holding this to be applied to the first unpainted type engine which we can get hold of which has to be subjected to type test. Will RHC{R. H. Coverley - Production Engineer} please arrange to let us know when he has a suitable engine, and we will arrange for it to be painted with this enamel instead of standard Cerric enamel which is now used.
