We have a pair of these magnetos Nos.98033/4 with the latest modifications, and we would like these to be fitted, at RG{Mr Rowledge}'s request, to a development engine for test. These magnetos should require no extra fitting work other than adjustments to the contact breaker control arm. They should be fitted with braided cables and this will be found to be a much easier job w than with B.T.H. magnetos. The two B.T.H. magnetos which these machines will replace should be returned to us. It might be mentioned that these magnetos would be especially suitable for any high speed development work.
