| To By. {R.W. Bailey - Chief Engineer} from RM {William Robotham - Chief Engineer} /NRC. {N. R. Chandler} 612 Rm {William Robotham - Chief Engineer} /NRC. {N. R. Chandler} /MR.11.11.37. WRAITH III AND BENTLEY III CLUTCH. With regard to the arrg. drawing GCD.2 of the above clutches, we recommend using Borg & Beck 11.A.3 and 10.A.3 assemblies exactly as now used on the 25/30 and Bentley. We do not think there is justification for the extra cost of the 11.A.6 and 10.A.6 ventilated assemblies, as no trouble with these clutches has been traced to overheating. As a matter of fact, the ventilated and unventilated assemblies are interchangeable in every respect. Rm {William Robotham - Chief Engineer} /NRC. {N. R. Chandler} | ||
