Those numbers sound correct. The lenghts you might be missing from your list are the symetrical spindles used for track cranksets or later road cranksets such as Chorus and Athena. Those will be 109.5 to 111 millimeters long.

What puzzles me now is the 74mm BB that Ted Ernst mentioned. I've never seen one. Did they really use thin-wall cups? I could see those having thick-wall cups, in which case they could use the same spindle as the 70mm thick-wall. Or perhaps it's time to start re-measuring everything in my BB spindle collection...
