as regards drive chain -
thank you for the foto. the ebay listing gives a closeup view of the machine's chainset. chain is seen to be something other than SEDIS. there appear to be markings on the plates but just not eno' "rez" to make them out...
looks to be the wrong colour for a Renold. the plate edges are chamfered but not really beveled as might be seen on a premium drive chain.
have no guesses as to maker.

as regards Selection Tricolore Course/STC -
the frankish cycle industry had had two competing export groups for a number of years. they were known as FREXA and as GEFFAC. IIRC 1973 was the launch year for the STC concept.
Campag was in a position of great leverage with racing teams. because they "made everything" (or nearly so!) they could "sponsor" the pro teams but with the caveat that the team could not employ a single product which in any way competed with a Campag one. the French cycle industry was at a disadvantage in this regard as there was no one maker of fittings in their industry which was as comprehensive and dominant as Campag was in the Italian industry. hence the creation of STC in an effort to compete.

as regards Maillard, Perrin & Verot they are interconnected going back decades. perhaps the single most pivotal individual was Achille Haubtmann. there has never been a "Stronglight Co." per se. the name was one for a product line. in its earliest incarnation one of its brand names was simply "Strong." the maker was known variously as Etablissements Verot (for Laurent Verot) and as Etablissements Verot-Perrin.
for any readers with an interest in the history it is gone into in good detail with excellent documentation in this discussion thread at the Belgian cycle forum veloretrocourse -
