I just received my first Esterbrooks. One was identified as a J Series double-jewel, as shown here. It has "BELL SYSTEM PROPERTY" engraved, just like the engraved example shown on that page, in black.
There is some goo on the cap that looks like a label was stuck to it.
Before I fill it, should I soak the tip in water? Should I take it apart to see if the sack is OK?
