Here we have a no name bchr eye dropper fountain pen. It is not restored to the extent that i have not cleaned the inner barrel. I do not see any cracks or chips that would hinder a seal. However, as is this case with many slip cap style vintage pens, there was an error in this listing. This unbranded pen does not have any cracks in it i was mistaken with another pen i had.The body is browned and discolored as is normal. You can still feel the chasing. The main shining point of this pen is the nib. I don't use the term "wet noodle" lightly.
There is no steadfast rule on when it can be used, but i consider dip style steel nibs or some victorian dip style nibs that require 180-220 grams of pressure to be wet noodle. The type that is hard to control if you aren't good with controling pressure. As a reference point an average waterman #2 nib requires 350-375 grams of force closer to 400 if you really want to push them to the limit which i prefer not to do. Something like a noodlers flex pen to get some character in your nib, that requires roughly 300 grams of pressure (character here would be some slight variation you might want to see in a soft springy nib for signature/writing). In order to really flex your ahab pen to do some calligraphy it requires over 600 grams of pressure, the kind of pressure that will leave imprints through multiple pages.
So If you're use to flexing modern steel flex pens, if you use the same force you will definitely break this nib for sure. This nib is rated at 270-285 grams according to my tenth of a gram digital scale.
The largest swell in the photo was produced with maybe 315 grams of force, but this would be the limit of the nib. This nib is not 100% fully aligned as is the case with many vintage nibs, but if you're skilled enough you can definitely fix this. However the sample writing was done by dipping the nib, so even with imperfect tines writing is 100% totally possible. The main benefit you might get is that bettter alignment and fitting would allow you to write more consistently without the rail roading.
The sample with gaps in the ink is when i started to write faster. If you keep the angle lower and write slower, you can obtain the swells shown.There is some light scratches on the nib as shown, but i don't see it as deep enough to affect the integrity of the nib in anyway, just cosmetic damage. There is a healthy amount of tipping material on this nib for years and years of future use. It is a highly visible coating. The geometry of the nib appears to be in tact, it does not look like this nib was sprung at all, as it springs back quickly in contrast to a weak sprung nib that never gets it's spring back.
If you wish to return it please do not modify the pen in anyway. Feel free to dip it and test drive it though, just make sure it is a safe ink like say a waterman ink.
If your ink eats into the rubber feed or clogs it, i will not be able to accept it back. Modern waterman inks are super gentle and great for test driving vintage pens.
