I have replaced sack and presser bar in a newly bought pen. I can't find any brand or logo, except for the initials PP on the 14 karat nib. I think the resacking works, but I doubt the presser bar optimally pushes air out of the sack. It works, it does take up some ink, but how to check or fix it? This is my first buttonfiller, lever fillers seem to be a bit easier.
