| RR 755 (10M) (DB{Donald Bastow - Suspensions}130 12-9-24) MS 301225 COMPLETED 14.6.26 STANDARDISATION of CHASSIS PARTS. Date 31.5.26 X No. 4079 Drawing No. Part List Description of Parts: Moulded Redmanol Case for Ignition Coil. Origin: Reduction in cost of manufacture and improvement in appearance of coil. Experimental Test Report. See EFC1/T4.10.24, EFC3/T 4.5.24, EFC2/T23.9.25, EFC2/T4.3.26., in addition to which a finer primary winding coil in Redmanol case has recently completed a 10,000 miles test on chassis 10-G-111 with entirely satisfactory results. In all, this coil has done 14,000 miles. A further Redmanol encased coil (with standard winding) not explicitly mentioned in our previous reports. Road Test Report. has now completed 23,200 miles satisfactorily. The moulding plant at the Works has ample capacity to produce these coil cases. It is proposed to make a simple production test to ensure the quality of Redmanol remains constant. Weight of Old Part. Weight of New Part. Difference per Car. Cost of Old Part. 12s. 11d.

BAILEY | 2.6.26 | This change is dangerous - a change in quality or source of supply might easily land us in serious difficulty. I like the finish of the synthetic moulding, but think risk run is too high to justify a change. BY.{R.W. Bailey - Chief Engineer} MR. PLATFORD | 31.5.26 | Agreed. EP{G.
