Filled it this morning, after cleaning even more cruft from inside the barrel. Section is in place in the barrel and holding without glue, which is preferred.Fairly bold nib, somewhat flexible. So far, so good. But I am storing it vertically, nib up, just in case.
(Still working to get my Palmer Method cursive up to spec -- and then it's on to Spencerian! BTW, the radiogram form is a reproduction).
