Vintage Waterman Inner Cap Leak

[scribe16]

Hello there, I have had a bit of bad luck lately with a couple of antiqe waterman's that I recently acquired. Both pens have started leaking inside the cap to the point that ink gets everywhere and even down onto the section.

 

On close inspection I can see that the inner cap on both pens is distorted. So the inner cap is no longer round and doesn't seal properly and on both pens I can see a spot where the inner cap has pulled away from the wall of the outer pen cap.

 

Both pens are BHR from the 1920s

 

does anyone have any experience with this problem and ways of fixing it?

 

Thanks.
