| 18.12.26. -2- Contd. Now that the magneto is fitted in a position where the temperature is lower we think it would be advisable to revert to ebonite and are making moulds for this material which will produce a mechanically stronger pick-up than the original one while retaining the advantage of this material as an insulator. Yours faithfully, FOR AND ON BEHALF OF NORTH & SONS LTD. (sgd) C.H. Kirby, DIRECTOR. [Watermark: DICKINSON BOND 1804 MADE AT CROXLEY] | ||
