I have recently inherited a Montblanc pen from my mum who passed away just before Christmas.

I know it is a Meisterstuck however beyond that I know very little. Pictures below.

The pen appears to leak from the base of the nib into the cap which then makes its way onto my hand during use! Is it a repairable fault? If it's something I should get repaired (I definitely will due to the sentimental value) where should I take it in the UK (or send it off)? The pen is always stored in the case and not shaken around so I'm hopeful it's not just me!

Thanks
