Well done Mike,
Once you get too it, fixing "51" nibs is not too bad. From my limited experience, the first thing I now look at if a "51" is not smooth is the alignment of the nib. It has surprised me just how robust they are and how much flexing they can take.
Once you get them back into shape, they just write wonderfully.
And you got yourself off the hook with 'Herself' that has got to be a double Whammy
Why don't you buy another pen whilst the going is good?
Jim
