| BUY 272 Agents Copy RR FB/EHF. 67260/67449 AGC/CEM. 1st June, 1938. Messrs. Dennis Bros, Ltd., Guildford, Surrey. Dear Sirs, Attention of Mr. Milne. We thank you for your letter of the 28th May enclosing blue prints X1076, X1077, X1078, X1079 and X1081 in connection with bearings in Aluminium-tin material. The question of price for 100 sets and alternatively 500 sets of these bearings has been handed over to our Sales Department who will be writing you in due course. With reference to your letter of the 30th May, Ref. JM{Mr Morley}/CS, in connection with centre main bearings Part No. 34445 to be made in RR. Aluminium-tin Alloy, we confirm 'phone conversation of today's date in which we are proceeding with the production of castings, heat treated and machined on the outside diameter, leaving the bore and the faces to be finished off at your Works, when assembled in the housing. This, from our point of view, will greatly facilitate the time taken to get this job through and by this means it is hoped to get the bearings off to you in a matter of 6 or 7 days after receipt of the material from High Duty Alloys. Regarding this last point, you will remember the writer mentioning to you that we had changed from the AC.6. to AC.9 material as the result of experiments carried out by Rolls Royce, and also with one other Commercial Vehicle Engine Builder in the London area, proving that the AC.9 was a very distinct step forward on this type | ||
