Hello, I am communicating to all of you who have great experience in these pens. I just purchased my first vintage pen parker 51 aerometric condition near mint restored from a reliable website. But the problem is that the pen has a miserable ink flow like I've never seen, an extremely dry flow that makes the black ink look gray like a very soft pencil. It is also worse in my case that I write in cursive and fast and my loops look terrible and feel rough and look dim. And my question is if I'm supposed to have bought it restored so it's clean and free of obstructions or is it a problem with the nib? I feel quite nervous and disappointed honestly I like the grip and design of the pen but its performance is the worst felt in a fountain pen. And this happened with the most wet ink I have, I can imagine the terrible result with a dry ink = 0
