This isn't what it looks like

Yesterday I dropped an ink bottle onto this pen. I thought it had survived, up until it leaked ink onto my hands during my livestream.

The body is cracked.

What it looks like I'm about to do is disassemble a Montblanc Meisterstück LeGrand instead of paying the €80 fee to have it repaired in Hamburg, using the tool specifically designed for this pen. The tool is proprietary, not for sale, and very much not approved for use outside of the factory.

Then I'm going to cautiously heat the body with a heatgun and a soldering iron to heal the resin, avoiding deformations if I can.

After which I'm going to carefully squirt a droplet of biopolymer from the bottle into the wound using a hypodermic. The biopolymer was extracted from lac insects in India before the advent of synthetic adhesives derived from petrochemicals.

Finally I'm going to gently polish the wound with 1 Micron (12,000 grit) micro-mesh and reassemble the pen.

This is the point in the story where Fountain Pen enthusiasts are having heart palpitations. The thing about Montblanc is their service: your great-great-grandchildren can hand over your pen at a Montblanc boutique anywhere in the world a hundred years from now and Montblanc will send it to Hamburg for service and repair, for whatever amount is equivalent to €80 then.

Unless it has undergone an invasive surgery such as this one. Montblanc strenuously objects to the use -and even possession- of the tool and won't service a pen upon which it has been applied.

Fortunately for me the Montblanc tool is also the right tool to disassemble this Chinese counterfeit. And in fact, the only method of returning this pen to working order available to me.
