| To E.{Mr Elliott - Chief Engineer} from EFC. EFC8/T19.8.18. X. 3290 RE NOMOGRAMS Referring to your note E1/G27718, we are pleased to hear you found these useful. In making these up again for greater accuracy, we propose increasing the size, but before starting we would like to know if the sizes we are considering will be suitable for you. We propose exactly doubling the size of each sheet so that the small one will become what we ordinarily know as size 4 and the large one will become a double size 4 which is rather larger than what we ordinarily call size 5. We suppose that when you wish to use these, you will pin them on to one board, and therefore, we would like to be sure before making these up what size will be most suitable. You would, no doubt, like to arrange these side by side on the same board when using them. Will you kindly let me know this, and then I will make a start on laying them out. EFC, | ||
