ROLLS-ROYCE LTD. INSTRUCTIONS. To Order No. Customer's No. performance on the leaky gap would be considerably better. The low speed performance is particularly good. This magneto does not appear to have the slow make cams fitted as the timing of make only shows an average variation of 3 1/2° with an increase or decrease of .004" in the primary gap. This as we have previously pointed out to messrs North's could be 10° or more. Signed H.E.W. This Sheet must be filed on completion of the work. RR 238 (150 BKS.)
