Thanks for the feedback. Yes, the BB is at best an interesting paperweight.
Re stay damage: when the bike came to my friend the pictured damage was already done. The bike came in with all three chainrings installed installed on the triple - the granny was removed as a part of his rebuild before he sold the bike to me. As I think about it more, the fact that the small ring shows damage that is uneven circumferentially would support the BB being...compromised before my friend and I came into the bike; the play in the BB allowing chainring rub during the NDS power stroke.
Either way, I gave it a heck of a twist during the aforementioned incident, perhaps turning bad to worse. I'd say the ultimate failure was initiated by a local failure at the above bearing race in the sleeve.
I was hoping to reuse the spindle, and it turns out I have a pretty decent set of Sugino cups and bearings in a box here. Unfortunately, the original spindle will not work with typical BB cups due to the lack of a 'cone' (i.e. bearing race lip).
The search begins. Thanks again.
Edit: When the bike was reassembled, the BB was pushed as far to the DS as possible, not sure where it was originally.
