I found on investigating the matter that your instructions had been passed on by Mr Nadin to Mr Spinney and that he (Mr Spinney) has been into the question of gauges but he has found that the resulting gauge would consist of a piece of wood only 1 5/8" high. Apparently his instructions were to provide a gauge over which the car would pass when the frame was loaded in such a way that the buffers would be compressed about 1/2". Mr Spinney reported to Mr Nadin these facts and asked for confirmation of his instructions as they did not appear to be reasonable. Mr Nadin replied to the effect that he did not consider it necessary or advisable to raise the matter with Mr Johnson.

This was the position of the matter when I investigated it in accordance with your attached memorandum, and in discussion with Mr Nadin and Mr Spinney we have arrived at the following conclusions:-

1. A simple straight gauge of height equal to the minimum clearance is not a solution of the difficulty because it will only gauge the lowest point, i.e. the silencer outlet, and will take no account of such an important part as the fly-
