| 6017 By. {R.W. Bailey - Chief Engineer} From Hs {Lord Ernest Hives - Chair} /Wst. c. to Sft {Mr Swift} /Mr.Brock. Hs {Lord Ernest Hives - Chair} /Wst.7/MA.20.9.35. Re. SEEKAY WAX FOR IGNITION COILS. Mr.Brock has raised serious reasonable objections to the filling of ignition coils by hand with high temperature chlorinated wax such as "Seekay". He considers the only safe way is vacuum impregnation. Upon further consideration and after making further tests on two other coils we are now prepared to agree to wax impregnation as the advantages gained by the sealing off of the coil outweigh the slight reduction in performance.
