Definately an NR with pantograph fluting. In fact, if there's a "B" on the front it's a Bianchi panto post.
The easiest way to distinguish between the first generation Super Record and a Nuovo Record seatpost with fluting:
SR - bottom cradle pivot drilled all the way through
NR - solid
SR - bottom cradles alloy
NR - steel
SR - fluting fades to more of a point - just like the later SR one-bolt posts
NR - rounded-end fluting
SR - thinner steel top clamps
NR - thicker
SR - post wall thickness is thinner, too
Hope that clears it up for you (a Bianchi panto NR post is still worth some big bucks, and has a cool factor for sure).
