This pen was in excellent condition when I acquired it, needing only a good cleaning, a new ink sac, and repair of a hairline crack in the cap lip.  I used Loctite 480, which is frequently recommended on Fountain Pen Network, to glue and fill the crack, which is now quite stable and almost invisible, even with a loupe.

The nib is a Conklin Toledo 4, flex from fine to broad, but not a "wet noodle".
