| S/W. {Sales / Derby Works} SECRET. Y 5970 To H. {Arthur M. Hanbury - Head Complaints} from Eg. c. to Ser. Hr., Mr., [illegible crossed out text] SgS/DS.8.21. re J.3. Many thanks for R7/M4.8.21 and I note that the full and latest size Japan(Experimental Engine) has been called No. 5. This makes the matter clear. I think this name, i.e. Japan(Experimental Engine) 5, will serve quite well, but I would not, of course, propose to use it for sales purposes, - only for internal identification prior to production. Whether we give the car a name or not can be left for future consideration, but personally I am not very keen. The 20/25 has earned valuable good will for itself and it would, I think, be a pity to lose any of it. I am glad to note you agree that we must make a model as soon as possible and that you were writing to the same effect prior to the receipt of my memo, and I am also very glad to note that you and E. {Mr Elliott - Chief Engineer} have arranged to go ahead with this with all possible speed.
