It has been repaired! Geoffrey Berliner of Berliner Pens in New York (I wasn't too enthusiastic about a multi-month wait) got it back to me in 6 days.
It is not a pretty nib, except from afar, but it is a lovely writer with a bit of not-bad tactileness. I never had the pen pre-damage, so I cannot compare the repaired to the original. I also get the envelope he gave it to me in, which has the information written on it with a beautiful Black-Black-Blue, which he laid down with an incredible silver overlay Waterman with a flexy nib.
I will definitely be using this pen often.
