| X6058 HS{Lord Ernest Hives - Chair}/Wst. SFT{Mr Swift}/EJB1/EG.14.4.32. The Parafin Wax we use for dipping the ends of the Ignition Coils and which we originally obtained from Messrs. Symonds usually arrived in such a filthy condition that it was thought advisable to change the source of supply. Herewith two samples, one from Messrs Symonds, and the other from the new suppliers. Will you please make tests of these, and instruct which is the best for our use. My personal opinion is that we should use Halowax which is made specially for insulating purposes.
