I'm rebuilding a logotype that uses this sans serif that looks a lot like futura but differs in some subtle ways:
* The lower case s upper and lower hooks flow in a more symmetric way and is a bit narrower.
* The lower case acute accent on the letter i is different in shape with horizontal top and bottom terminations.
* Round letters are a little bit wider.
* The counter of the lower case a and p push very deep into the stem.
I have Linotype's, Adobe's and Bitstream's and they don't look like this. I also googled Futura ND and it doesn't match either.
