Robert Broderick (the King of Katalog scans) has 7 catalogs for viewing on his Velo-Pages site
MAVIC
and our beloved VeloBase also cross-references to 4 of Robert's scans, the only one you are likely to want is his latest from '84-'85, but the earlier ones are interesting to us amateur historians.
I personally have a catalog from the late '80s (not sure of exact date cause there's not copyright info on it) that I have never got around to scanning, but maybe I can be influenced...
I can tell you it does NOT answer most of the questions that Brandon98 poses, but the 610 BB came with spindle lengths of 112 (track), 114 and 116 (double and "double long"), 119 and 123 (triple and "triple long"), the ATB BB 616 has 3 lengths: 124, 128 and 134. My guess is that the taper is ISO for all, can't confirm if the spindles are all symmetrical, but the mechanical drawing seems to hint that they are not.
