On Monday I met Mr. Humphrey Symons and learned that he had been loaned Mr. Jack Barclay's Trials P.III over the last week-end. Whilst Mr. Symons was delighted with the car in general he was very disturbed about the brakes which he found to be inefficient at slow speeds particularly after braking from a high speed. His first instance of this was where he was on a road which he knew quite well and he started to slow up at what would be a normal distance for a side turn without any need for severe braking, he found, however, that doing the best he could with the brakes he still could not make the side turning. Mr. Symons' further experience of the brakes on this car decided him to report the matter to Messrs. Jack Barclays when he handed the car back. I have reported this because I do not feel convinced that it is just a matter of adjustment coming on the top, as it does, of the calamitous figures quoted in the description in the Autocar of a run on a P.III by the Autocar's Test Staff.
