Dear Sir, Reverting to the interview our Director, Mr. Cecil Allen, had with your Mr. Hives on the 5th instant with reference to the results obtained from the trial set of 'Allen' Pistons supplied you some months ago, we understand that you will be good enough to advise us in due course when the cylinders in which these pistons are fitted are being lifted so that we may send up one of our representatives to see the pistons drawn and examine cylinders etc. Perhaps you will be good enough to give us as long notice as possible when you propose dealing with this matter so that we may arrange our visit accordingly. Thanking you in anticipation, and hoping you will be prepared to carry out further tests with the 'Allen' Pistons, which we are confident can give you highly satisfactory results. Yours faithfully, FOR ALLEN & SIMMONDS (READING) LTD., [Signature] | ||
