| FROM R.{Sir Henry Royce} VIEWED C. to MC. BSS. C. to D.W. MS. re BENSPORT HEAD. J.F. & BENSPORT GEARBOXS. R1/W21.5.32. X 4592 Y 5310- I think your latest suggestion is the best - i.e. all heads looking one way, both in the exhaust and inlet. For instance, if the inlets all look forward, the exhausts all look backward, and vice versa. We think it would be better to swallow the want of looking glass symmetry for the sake of the plugs, and one believes the best cooling of the whole head. I also agree that the open type head would be better for this small engine at least. I am inclined to think that J.{Mr Johnson W.M.} F.{Mr Friese} should be treated similarly. I would have spoken to you myself over the telephone, but have gone to 'Canada' to push forward the gearbox work which is pressing, (both the central change Bensport, and the L.M. J.F.) These will want somewhat similar treatment as regards the tower mechanism. J.{Mr Johnson W.M.} F.{Mr Friese} is standing still for Bensport, but the latter will be finished I think this week.
