Hi all, I bought a NOS opera club recently with a Medium Palladium nib. It lays down a great and wet line. The only problem is, the ink gets drier and drier and finally it will be completely dry although there is still ink in the converter. What I have to do is to tap the nib a few times on paper or prime the nib and it will write again for a while. These writing cycles are typically for 4 pages on my A5 journal. Visual inspection on the tines does not look like anything wrong and the nib and feed seems to be aligned properly I brought the pen back to the place where I bought it and the repair person introduced a small spring agitator into the converter of the pen. I did not like this because when the pen is riding in my pocket for a while, a lot of ink ends up inside of the cap until there is a black ring around the pen. The first time I noticed these symptoms I used Iroshizuku Pilot ink, then I used Diamine black Oynx. Any help is greatly appreciated as other than this small problem the pen writes great.
