Subject: [CR]Straight post clamps and Nervar cranks

I have a couple of questions for the list.

First, someone commented recently about a seat clamp on a bike coming "upside down" and the top of a straight post contacting the bottom of the saddle. I presume he meant the type of clamp with two toothed flanges on each side, the whole thing being held together with a single bolt through the middle. By "upside down" I think he meant that the outside flanges are rotated such that the saddle rails pass below the clamp bolt rather than above it. Maybe I've been doing it wrong for years, but I always though this "upside down" configuration was the correct one. The reason I believe this is that on the classic crested Simplex seat post which secures the rails in a very similar manner, the rails pass below the clamp bolts, although this post has one clamp bolt on each side rather than a a single bolt. I think the problem with the post touching the saddle was that the straight post on that bike did not widen below the clamp, not that the clamp was upside down. Does anyone agree with me or am I the only one doing it wrong all these years?

Second question - I have a couple of Nervar cranks that are identical to the Nervar Star, except that the outside ring has the very small circle shared by TA Cyclotourist and Stronglight 49. The inside ring , which bolts to the outer one, is 128 BCD, identical to the Nervar Star rings. On the arm, where the Star is stamped "Nervar Star" in script letters, these are stamped simply "Nervar" in the same script. Anyone know what the name of this model was?
