Hi All...I am having a rather odd problem with a recent used M800 I purchased from the 90s. It has a M nib and I am a leftie, and the pen has been filled with brown Pelikan ink that I currently use in all my pens.
When I write with the new pen, it moves back and forth as I write with putting very little ink onto the page, i.e. very dry, or sometimes very light, to putting normal amount of ink down as one would expect from a M M800 nib...it goes back and forth like that, very light almost no ink to normal ink.
My first thought is that it is a problem with nib/feed, just doesn't work with my left hand, has been worn in differently, etc. So I take first a F nib from another M800 that is currently inked up and then another M nib from yet another inked M800, and try these nibs in the pen...and guess what, same problem! Then I used the nib from the pen I just bought in one of the other pens, and no problem either. So I concluded the problem does not lie with the nib/feed, but is caused by something else.
So I cleaned the pen out thoroughly and re-greased the piston with silicone in case there is some sort of seal issue that I will hopefully fix by re-greasing. But no luck, the problem still occurs, regardless of what nib I use in the pen.
So I am hoping that Pelikan experts here on the forum can perhaps shed some light on what is going on and have suggestions as to what might fix the problem...very weird phenomenon...have not encountered before!
