| 1044 To By. {R.W. Bailey - Chief Engineer} from Rm. {William Robotham - Chief Engineer} c. HPS. {Horace Percy Smith - Experimental Factory Mgr} Rm. {William Robotham - Chief Engineer} 12/MH. {M. Huckerby} 28.7.38. original in 1020 Attached is copy of note from Vandervell with reference to the camshaft bearings on the B.50 cast iron engine. These camshaft bearings were drawn with stepped diameters. We have since discussed the matter with Vandervell, and he recommends that we should make them of a single diameter as is now general American practice. The detail drawings, therefore, require modifying and we should like HPS. {Horace Percy Smith - Experimental Factory Mgr} to consider the best method of reamering, boring or broaching in position.
