At present no pistons in aluminium are passable but those fitted to 49 GB. - F.H.R. We should not standardise these parts until we have had further reports from W.Y. Ep.{G. Eric Platford - Chief Quality Engineer} and Hives, as to whether they are good enough for our chassis. - WOR.{Arthur Wormald - General Works Manager} Prefer to wait until further tests, i.e. Commander Briggs car - EP.{G. Eric Platford - Chief Quality Engineer} I do not think we should do this until further trials are completed - BY.{R.W. Bailey - Chief Engineer} I don't agree until a definate report on their behaviour has been made and a statement of a number of miles run - NA.{Mr Nadin} | ||
