| 10HH also 1269 To By {R.W. Bailey - Chief Engineer} /Ald. {F. Allwood - Experimental Design} from Rm {William Robotham - Chief Engineer} /Std. Rm {William Robotham - Chief Engineer} /Std.13/MH. {M. Huckerby} 1.12.38. Will you please detail for us as soon as possible, a water pump pulley for B.60 similar to EB.3925 but made as a machined aluminium piece instead of the present two sheet metal pressings. The correct angle of Vee is 26°, and the correct body width of Vee is .610. If possible these details should be made suitable for die casting. We want this detailing as soon as possible to test a machine pulley of this type in order to see if it helps us with certain belt troubles which we are experiencing on this engine.
