I just got a copper Esterbrook SJ and it is a very pretty pen. The nib is very scratchy. After cleaning and flushing the pen it took ink pretty well but when I tested it I ended up with ink on the tip of my index finger. There was ink on threads but I have not noticed it since then. The ink flow could be better. I was doing circles on a brown paper bag to see if that would smooth the nib and it really grabbed the paper when I went from left to right. The ink flow was very inconsistent. I started hearing some clicking and discovered the feed section is a little loose. I do not have magnifying glass to look at the nibs.
What's the first step? I've been reading about replacing the sac and I think I can do that but the scratching and the loose feed have me concerned.
Thanks for your help,
Matt
