Lamy 2000 (Vintage) Tiny Leak Around Clutch Tab

[eharriett]

I'd been holding out to get a Lamy 2000 until I found what I wanted, and I recently did. It is a vintage one. So old that the piston filler is clear with a green tint. And the Macralon has worn down to where the pen is almost completely glossy. And it has a nice wet M nib. Glad I waited until I found this one.

Except, when I first filled it, after a couple hours, there was a small leak. I very slowly traced it as far around as I could, after a bit of research, consensus seemed to be a crack in the section, but after 10 minutes with a loupe I found nothing. Before I traced the leak down I looked at everything and pulled the pen apart. Checked the metal clutch ring for straightness (its fine), to the o ring (not as supple as Id like, might replace), to the nib and feed (perfect). I very slowly rubbed my finger around the section seam and there is a pinprick leak coming out of one of the tabs. Not both, just one.

I could use some suggestions on how to fix this, or even what the problem specifically is.

 

This is a repost from the Q&A sub. No one had seen this problem before so I'm hoping one of you has and can advise on what I can do about it. Thanks!
