Rm{William Robotham - Chief Engineer}/WRC.9/JH.6.1.39. re Units B.V.5. and B.V.7. In order to avoid confusion in records, please note engine B.V.5. which was removed from chassis 8.B.V. about Dec. 2nd. i.e. between the two Continental runs, will continue to be known as B.V.5. The engine B.V.7 which is now in 8.B.V. will continue to be called B.V.7 although it now bears a temporary plate marked B.V.5, but this will be removed as soon as the car returns to DERBY, and the correct plate B.V.7. is to be fitted. We wish to make it clear, that for all purposes of record and memos. there has been no change of number, and B.V.7. is now on the Continent and B.V.5 is now in the shop.
