When writing this I noticed that George Newnes named his article the 'Luvax Bijou System' and I have checked my copy of the RSR WSM where it is called the 'Luvax-Bijur System'. To add further confusion the cap on Tilly says it is the 'Girling-Bijur Lubricating System' and from all this I can only assume that each and every system is the same. Also in this article there is an excellent topic on the 'Ripault' or 'Alcyl' system and though not Rover related I do not wish to split the article
