Re Chassis 93 NK.

We have continued our tests to-day.

The oil pressure gradually built up, and is now fairly settled at 25 lbs. pressure.

The engine on this morning's run tightened up somewhat seriously, whilst on the road, but became quite free afterwards. We shall endeavour to find out the reason of this to-night, if possible without taking bottom half of crankcase off. The engine was running quite good, at the start of the afternoon's run.

G.W.Hancock.

P.S.
We have received the Log Book for tyres, in parcel No. R.R. 13757.

We are enclosing summary of faults on 9 G.III. during the tests out here.

We have not made a general report on the completion of the trials, on account of not being here when the car left, but if you wish it, I can give you a fairly accurate detailed report.
