| Contd. -2- EFC/T31.10.24. up to date These are now all the points of complaint and we think that with these modifications there may be some chance of the whole system being O.K. If it possible for us to have these units first thing in the morning we may be able to pass them within an hour and a half and in time for fixing up on a chassis for test. In accordance with our usual practice in which units made for expl. purposes are given letters, and those for produc-tion purposes Nos., perhaps you would kindly have this first set of units marked with the letter A, and later units accordingly.
