| S/W X4613 C6/C16.1.29 Semi-Isolation. Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}8/LG3.1.29 -------- Semi-isolation only commenced on 40/50 h.p. chassis No. 77-WR, and on 20 h.p. chassis GFN-52 and there are very few cars completed yet. It is, therefore, too early to say, but we expect satisfactory results. C. | ||
