Dear all, I have a question about fully disassembling a Homo Sapiens pens. I am specifically interested in removing the packing unit of their power filler mechanism. I have not found one that has attempted it yet, and there seems to be no resource for any potential complications online. The pen is made so that the only thing you can take off is the nib unit. Even the blind cap has no notches to help you unthread it, should you need to. They like their pens sealed. Nevertheless, this can be problematic and challenging for us fountain pen folks, and we love a challenge. So I have some questions. Notice that my main concern really is with the material as I have not worked with their resins before and don't want to badly affect this pen that I'm working on. Like its glass transition temperature or its reaction to any chemicals. Has a full disassembly ever been attempted? This mainly refers to removing the rear packing unit. If so, what is the best method for removing it. I suspect the threads in the barrel might be glued. If so, what is the best method for weakening the glue without affecting the barrel resin? and what does Visconti use to glue it in the first place? (for when I put it back). My second question is regarding cleaning staining ink off the inside of a clear barrel. If there is anything you suggest I totally avoid on this resin please let me know now. any ideas welcome. Thank you for passing by. I'm looking forward to hearing any input on this. Best regards KR

Hi Everyone, I always use fpnibs.com as my source for JoWo nibs which they custom grind to whatever I want, but they don't offer Bock nibs. Is there anyone out that that not only sells Bock nibs but will also custom grind them for you? Thanks!

I just recently got an old Montblanc 24 from Ebay and I removed the nib unit from the section and there is ink trapped in-between the nib and nib unit. Does anyone know how to remove the nib from the nib unit? Or will I have to get a new nib unit(which I rather not do)? I can post pictures if needed.

What price do pen shops and retailers pay for an M800 before selling on to the end user? Just curious..
