Just looking for some guidance! I have had this pen for 24 years and whilst it still writes beautifully and never dries out (if in regular use) it has developed a leak when capped. At first I thought it just didn't travel well so i left it on my desk, but even then when i come to use it the next day, it has ink at the bottom of the front section. I then need to clean the cap out etc. I have obviously tried to check the nib and feed is in correctly, not that i know what I'm looking at. Is it worth replacing the bottom section and feed, it a gold nib so would want to keep that? Any help would be appreciated. Regards Nick
