Rm.{William Robotham - Chief Engineer} c. RHCT. c. RRD/BMSY. See me Rm{William Robotham - Chief Engineer} HPS.{Horace Percy Smith - Experimental Factory Mgr}6/VS.{J. Vickers}12.1.39. WRAITH. BONNET SIDE STRIP. Referring to BY/NS.{Norman Scott}10/C.10.1.39., a set of welded side strips and rest angles were fitted to 29.G.VI in August last and have since run 3,600 miles with satisfactory results. There has been no evidence of any tendency for the plates to separate at the weld and the scheme appears to be quite suitable for production, but perhaps Rm.{William Robotham - Chief Engineer} will say whether it is considered sufficient testing has been carried out to justify standardisation.
