Hi, I just got this pen off fleabay.
It is a very pretty pen, but it was a bit scratchy and balky unless the nib was wet. However, the line is smooth and very juicy!
Under the loupe I could see the tines were misaligned, and a bit of baby's bottom
However, the it is just possible to see above that the slit on the nib was twisted and the edges of the top of the nib were also out of whack; this could have been if one side had been dropped, or a repair job. I am puzzled. There is no damage evident anywhere else.
Anyhow, I got at the overlap with some 1200 grit wet and dry, followed by orange mylar and lastly a couple of passes of micromesh it is smooth as a
babys bottom, butter smooth, a fat line and still lovely juicy feed.
By the way, although I have a very nice camera with a macro bellows, these were taken with a modified fisheye adapter for my old iphone 3. It works pretty well
Oh, and for looking down pen barrels and into pen caps, this helps: It is a white LED wired to a little torch and heat shrinked to a copper wire. I can bite the battery to switch the light on with both hands free. Its it very handy!
