I have 36 tooth 128BCD, yes that's 36 tooth inner Nervar chainrings to fit the 128 bolt pattern for the outer rings that are TA Cyclotouriste compatib le. So, the inner rings do fall below the 40T (36 is the smallest for 128BC D).
These will be offered for sale on eBay shortly.

Yep, this is a Nervar Sport, which, like a Stronglight model 49 outer ring, is compatible with TA Cyclotourist arms. However, like Stronglight mod 49, th e inner circle is different, 128 for Nervar, 122 for Stronglight. So if you use a Nervar outer ring, you must use a Nervar inner ring - I don't know of anyon e else than made a 128 BCD ring. A 128 BCD ring should go down to 38T, but I've never seen one smaller than 40T.
