Brady numbers

The Brady studio numbered its work and I have been poking around trying to get a list of all the numbered photos - and information on whether any in the series are missing or rare. Any clues, dear reader?
Motivation: Have discovered a cache of Brady Antietams in an archive and don't know if it's complete or a fragment. Includes stereoscopic views.
In other Brady news, I'm scratching my head over this attempt to outdo Brady using virtual soldiers and a modern park setting.
