| ORIGINAL TO HS.{Lord Ernest Hives - Chair} FROM E.{Mr Elliott - Chief Engineer} Copy to C.I. EFC re. IMPROVED TYPE CONTACT BREAKER FOR STANDARD E.O.6 MAGNETO. Referring to the standardisation sheet for the above, no particulars of the magneto contact breaker are given of the altered type, only the performance. Before signing therefore for the standardisation could you kindly supply a model or a drawing of the new contact breaker so that we can see what it is like. It will be appreciated that performance on a given test alone does not justify standardisation entirely, as for example we should not think of using the Rudhardt type of contact breaker although it would most probably pass the same tests.
