I just acquired an Oversize Balance. The clip and ring have brown corrosion and the innards are shot, but it's so nice -- so big, and with such a monster of a large 14k nib. The kink in the clip seems to imply 1929-30.
I want to use it, and I want your opinions -- who are some trusted people to replace the sac and get it working? What should it cost? How much is it to get the brass issues dealt with? Is it worth it it?
In sum, am I right that it's a great pen to use? What would you do?
Thanks!
