You are correct about the Peugeot crank. That is a Stronglight model 104, 122 BCD, made from the late 70's to the middle 80's. The model number 104 is often marked on the back of the arms, even on the Peugeot logoed ones. This was one of the models that spanned the change from Stronglight 23.35 extractor thread to Campy 22.0 extractor thread. Occasionally you pick up a used pair with mismatched arms, so that you need to different extractors to remove the crank. Plus one arm might have French pedal thread, while the other has English. Boy is that fun!
As to the Nervars, the five arm model pictured on the box is the Nervar Star. The Stronglight 49 type has the same arm shape, but I don't believe it was a Star nor was it so marked. I have both. I beliveve I've seen the second type marked as Nervar "Sport", but I'm not certain of that. I'm pretty sure that the "Sport", or whatever its name, took the same 128 BCD inner ring as the Star in the same way that the Stronglight 49 took the same inner ring as the mod 93. Nervar also made a three arm crank like the TA Professional. I don't have a clue what that one was called.

I do not believe that it is. I believe these peugeot cranks were made by Stronglight. Here are two types of nervar star cranksets.

The first version is a 49bcd / cyclotourist type, which is personified in the actual crank in the box (is this the correct box? Note the big space for a 5-arm spider that goes unfilled). This crank shipped on '76 schwinn voyageurs (just checked the catalogue). The second version is the one personified in the picture on outside of the box, a regular 128bcd type. I think the second version is more common, and its the kind i had and the kind that shipped on raleighs.
The trademark of this crank is the diamond cutout in the arms, and spider arms that taper constantly (like late compagnolo gran sports.) This diamond cutout area of the arms have a rough surface that is difficult to keep clean.
