| RR 755 REVISED (10H) (D.C. 777-29-2-28) 315 C.L.Y. Completed 31.8.29. STANDARDISATION of CHASSIS PARTS. Date 16.8.29. Description of Parts: Wider Gap Radiator tubes. X No. 7250 Drawing No. Part List Origin: To reduce the possibility of radiators becoming blocked in service. F.2.B. series onwards. S. cars. Experimental Test Report. These tubes are 5t/7m/m.{Mr Moon / Mr Moore} as against the standard 6/7 m.m. tubes. They increase the water passage size 50%. Road Test Report. We have tested these tubes on the S.S. and can detect no loss in cooling efficiency. A similar test will be made on the Phantom before radiators are issued.
