Is the best name for this "RB545" or "RB.545" I don't know what "RB" is supposed to mean (Fedden Butler? 8-) ), but other Rolls engines seem to use the "RB.<number>" form. Andy Dingley ( talk) 10:17, 8 May 2009 (UTC) reply

It originally stood for Rover Barnoldswick, from the location of the Rover site that was working on (and failing with) Whittle's early jet engines. This site was 'swapped' with Rolls-Royce for a Meteor tank engine factory and the initials are nowadays regarded as standing-for Rolls-Royce (or just Rolls) Barnoldswick. —Preceding unsigned comment added by 213.40.249.9 ( talk) 12:02, 4 December 2009 (UTC) reply
