Roger is this the Lucas ‘Trafficator’ parts list you refer to: http://mgaguru.com/mgtech/books/pdf/L400e_sm.pdf
The rest of the parts catalogues are listed here: http://mgaguru.com/mgtech/books/lucas400e.htm – reading the ‘copyright’ page there is no issue with TOC making them available as long as a ‘credit’ is given to the source.
