| EXTRACT FROM LETTER RECEIVED FROM MESSRS.A.T.SPEEDOMETER Co.LTD., HRB/B. 21st May, 1935. We have noted here that on a considerable proportion of these flexibles, it is obvious that the flexes have been lying in stock in an unused condition for some considerable time, and this occasions the lubricant to become solidified, so that, when the flexible is fitted up to a car, noise results. We are thinking in particular of onebatch of returns of 9 flexes on the 16th April last, your Replacement Order No.R.8004, which were definitely from nine to eighteen months old. We use Price's Vasogene A.{Mr Adams} grease on these inner cables, and we have found that, so long as this grease is not allowed to lay up in stock on the flexibles for more than three to four months, it retains its correct consistency, but, if the flexibles are in stock for a longer period than this, it tends to dry up. | ||
