I have two Esterbrook J's that have been in the family since the 1950's, both were put away in the 70's and haven't been touched since.

The time has come to try to get them back on the road.

I can get the pens apart and have new ink sacs on the way, but I can't unscrew the nibs from either pen. I don't want to use excessive force and risk damaging the nibs or cracking the sections.

Does anyone have any suggestions about how to free up the nibs so they can be removed?

Thanks,

Mason
