| EFC. {E. Fowler Clarke - Electrical Engineer} X8796 BY {R.W. Bailey - Chief Engineer} /Cgh {W Clough} 7/G.25.1.28. WATFORD E.O.6 MAGNETO. We hand you herewith four Duralumin rocker arms for the contact breakers on the above magnetos. These rocker arms have been modified by Messrs. North with a view to getting a better method of securing the fibre blocks. We have had a few cases where the fibre blocks have come adrift on customers cars, and these modified rockers have been submitted by Messrs. North with a view to overcoming this fault. Will you please arrange for these rocker arms to be tested out, and let us have your report in due course. BY {R.W.
