GOSHAWK MAGNETO IGNITION FOR 20 HP. CARS. Origin. To provide alternative ignition. Taximeter Experimental Test Report. The Watford E.O.6. magneto will be used. The chief difference between running on magneto and battery is that with the magneto there is no automatic advance and therefore the hand control for the ignition must be operated as engine speed varies. Road Test Report. Run 1750 miles on 7-Goshawk-11. Fitted to 5-Goshawk-11 Run 100 miles. Drawing No. Part List A Scrap and replace at all costs, including Chassis already delivered to customers. B Scrap and replace on Chassis in works. C Scrap present stock and replace on all Chassis not yet handed to test. D Use existing stock Alteration effective on future Chassis. Cost of Parts in Works which will be scrapped if commenced on :- Series… £… Series… £… Series… £… Signature of Exp. Dept. that above is correct. E.Hives. Weight of Old Part. Cost of Old Part. Superceded parts. £ 2. 4. 0 per chassis. Weight of New Part. Cost of New Part. £ 17. 12. 6 per chassis. Difference per Car. Difference per Car. £ 15. 8. 6 increase. Storekeeper advised re above: Storekeeper's Signature Signature of Mr. De LOOSE that above is correct. My/JW 14.12.22. SIGNATURES | DATE | REMARKS Mr. JOHNSON (M.B.Johnson.) | 21.12.22 | Only a few required at present by our Depots and Agents for demonstration. Therefore #agreed Mr. ROYCE | 12/12/22 | Agreed. Only to be fitted when specially ordered. Not sure whether magneto can be safely removed for tappet adjustment even if fitted over seen recessed? FHR Mr. WORMALD | 8.12.22 | Suggest longer test before standard. Wor.{Arthur Wormald - General Works Manager} Mr. ROWLEDGE | 8.12.22 | Agreed. Rg.{Mr Rowledge} Mr. DAY | 12.12.22 | Agreed, but think rocking the magneto for forward & retard would improve the accessibility of the tappets. Mr. BAILEY | 11.12.22 | Agreed. BY.{R.W. Bailey - Chief Engineer} Mr. PLATFORD | 9.12.22 | Agreed on behalf of EP.{G. Eric Platford - Chief Quality Engineer} that some form of magneto ignition is desirable for cars going overseas, but do not consider sufficient running experience to standardize. J.A.M. Mr. NORTHEY | 9.12.22 | Agreed.
