If the difficulty of polishing the "nubbed" flutes is your biggest rap on Nervar, his is the answer:

This is a Nervar Sport triple, with Nervar, not TA, rings. The later, probably 70's, arms have smooth flutes with "NERVAR" in raised letters. I also have two 3-arm 116 BCD Nervar cranks with the same style arms.

The inner ring TA chainring bolts (middle set of bolts) are the ones I sought in a previous post. They have slotted heads like the large-ring-to-crankarm bolts, only slightly larger. They are slightly longer than the newer allen head bolts which were made for rings with countersunk holes.
