| - 2 - We note that in paragraphs 3 and 4 of our letter of December 29th, we refer to the break occurring on the opposite cam to that on which it occurs in the Model F.O.6, when the timing mark is visible through the window and would point out that the alteration made by replacing the distributor arm with one similar to that used on the Model E.O.6 reverses this condition and with the new rotor arm the break will occur on the same cam as in the Model E.O.6. We have looked into the matter of the rotor arms fitted to magnetos Nos.99171 and 99802, and find that these were delivered before the drawing referred to was made and were fitted with arms made for the E.O.6 magnetos which will be common to the two types of magneto. Yours Faithfully, For and on behalf of NORTH & SONS LTD. C.H.Kirby (sgd) Director. | ||
