There has been many problems with Noodler inks over the years......have they been cured?....I don't know....but some Noodlers users will not hear a word said bad.
Well Bay State Blue...was fixed so it no longer ate feeds faster than it stains pens....
They insist that some national research laboratory prove that. ...not willing to take the word of experts .
There are well known respectable repair men who will not warrant the pens they have repaired for Noodlers inks. Rick Propas(sp) the Pelikan guru once said that.
Supersaturated inks like many of Noodlers have been blamed for eating rubber sacks of lever pens with in a month!!!!!!!!!!!!!!!! Ron Zorn commented on that.
Once a rubber sack was good for 30-40 years....now only ten.
There were other professional repair men who have seen many hundreds of pens that had problem pens they blamed on Noodler inks.
They Bashed Noodlers..............maybe they had a reason.
Many folks once had problems with Noodlers that they wrote about that.
They either no longer use Noodlers or clean the pen after every use.....which one should do with any supersaturated ink....including Parker Pennmann.
I can believe that that roughness could be normal....but won't take apart my Persona or Joy to find out.
The bottom of the modern Lamy feed looks '20's fast. Peningeneer who helped develop that feed to go with the then new Safari or other Lamy pens, says they have to soak the feed in chemicals to roughen up the feed so it's as rough as sawn Ebonite.
Ask Lamy....send an Email with the picture of the nib....if it is not normal they will send you a new nib....or may ask you to send the pens so they may examine it.
Lamy is not fast with Emails nor return, but it is free.
