| RR 755B (10H) 88620 12-8-35 W.H.K. 21800 COMPLETED 3.12.36. BENTLEY STANDARDISATION of PARTS. Date 23/11 28.10.36 X No. 206. Drawing No. GB.2174. Description of Parts: FRONT DRUMS WITH INCREASED RIB HEIGHT. Origin: To reduce the number of quarterly complaints about Fierceness, Diving, Squeaking and Inefficiency. Report of Experimental Test. This alteration to the machining of our present castings was going to be standardised once before, but was thought to be unadvisable as it might have made judder worse. Now that N.Sch.4865 is going on production, this no longer applies. 5-B-IV ran 10,000 miles with drums having larger ribs.
