| RR 755 (10H) (SL391 2-11-23) MP 281297 COMPLETED 12.7.24. STANDARDISATION of CHASSIS PARTS. Date 7.4.24. X No. 4240 Drawing No. Part List Description of Parts: RADIATOR & SHUTTER. Origin: To improve appearance and design. Experimental Test Report: New radiator with shutters incorporated in the radiator. This radiator gives a greatly improved appearance. Owing to the depth of the radiator tubes being reduced from 4" to 3.5", the radiator is slightly less efficient (approx. 5%). Capacity and weight approx. the same, see Hs{Lord Ernest Hives - Chair}3/LG4.4.24. Road Test Report: Run 11,250 miles on 6-GII - no trouble. Run 3,000 miles on 5-GII - no trouble. Handwritten Note: It has now been agreed that the present std. Matrix as on the present car shall be retained for this new Radiator. Action boxes: C: Scrap present stock and replace on all Chassis not yet handed to test. [TICKED] D: Use existing stock Alteration effective on future Chassis [TICKED WITH X] Weight of Old Part: 67 lbs. Weight of New Part: 63 lbs. Difference per Car. Decrease: 4 lbs. Cost of Old Part: £ 25. 4. 0 Cost of New Part: £ 26. 8. 0 Difference per Car. Increase: £ 1. 4. 0 Signature of Mr. DE LOOZE that above is correct: My/Rhs. SIGNATURES: MR. JOHNSON, 11.7.24, Agreed.
