Ultra Rare and coveted Titanium bottom bracket from the mid to late 90's from North Carolina boutique CNC parts builder Bruce Boone.  These were released with the famous "Twist" crankset.

Good overall condition, some corrosion on the lock rings/outer cups but inner races and spindle is in great shape.  Note that there is some marring on the cup threads but is very minor and lock rings thread in fine.  These could easily be chased to a finer texture.  Bearings are pretty smooth but might want to replace soon for ultimate performance.  Also, as can be seen in the last picture, the right side lockring is cracked.  This is probably from removal and it seemed to work fine but would recommend replacing this as well.
