Date: 9.5.24 No. X 2752 / 516 Drawing No. Part List Description of Parts: ARRANGEMENT OF DYNAMO AND MAGNETO DRIVES. Origin: To suit cars fitted with 4-wheel brakes. Experimental Test Report: The Lucas dynamo is modified to suit double ended drive. The drives are similar to those used on 40/50 and 20 HP. except that they are made in N.S. instead of C.H.N.S. The hardening causes distortion on the C.H.N.S. The N.S. shows no sign of wear after 10,000 miles. Road Test Report: Fitted to 98-NK - run 10,000 miles. Fitted to 9-PK and 35-PK Run 3500 and 1800 miles respectively. No trouble. Options: 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 Weight of Old Part: Weight of New Part: Difference per Car: Cost of Old Part: £ 71. 12. 10 Cost of New Part: £ 72. 10. 0 Difference per Car: £ 17. 2 increase.
