New to the forum but I am in love with Esterbrooks. I found my first one in the wild last week at an antique store in a small "1 horse" town. The owner still had the original box and instructions and it comes with a sunburst 3550 nib. It had one bad scratch on it other than it seemed to be in near perfect condition. So the $25 price tag was easy for me. The sac was still intact when I opened it up, but I replaced it cleaned the feed, and was able to remove the scratch. It is now polished and writes well. Wanted to share with you all my find being one of my first posts.
