Dear Mr. Robotham, I have been much interested in the various reports which Mr. Bowrey has submitted after his interviews with you. There are three minor points on which I would like to learn of your experience in connection with thinner oils:- (1) Do you find noise has increased, especially of the valves? (2) Is there a bigger consumption on the one shot lubricator? (3) Do you find any tendency to clutch slip? I take this opportunity of thanking you for the courteous attention which you have extended to our Mr. Bowrey. I am hoping before long to be in the neighbourhood of Derby - perhaps next week - and would like to call upon you but I would advise you more exactly in due course. Yours sincerely, A.{Mr Adams} Duckham | ||
