| X.4284 D. {John DeLooze - Company Secretary} Extract from Cy1/G7321. X.4275 - AMERICAN BOSCH BATTERY IGNITION. In continuation of my letter of March 4, 1921 on this subject, replying to Mr. Royce's letter of Feb. 16th I wish to add the following notes :- X.4284. Referring to the Delco distributor, we believe that this company does not now use Bakelite for any distributor tracks, this practice having given the makers a great deal of trouble in the early days. We think Mr. Royce will find that all the Delco distributors are a special sort of hard rubber. | ||
