| JH/KES - 2 - 28th November, 1939. W. A.{Mr Adams} Robotham, Esq., (contd). is interchangeable. There is no top or bottom half and every one is within .0003 for radial thickness. I am enclosing you a blueprint showing how we should make it and if the price of about 5/- for the pair of bearings would be reasonable, I should be very pleased to put in the tools and make you some up. Does this seem at all interesting to you? Yours sincerely, Jhn. Howlett | ||
