Montblanc 144 from the 1950s nib exchange

You can buy the tools on my homepage:

I had to change the nib on an antique Montblanc 144 from the late 50s. Unfortunately, the old nib was completely worn down, so there was no iridium dot left.
I unscrewed the nib with a special tool and then drove it out with the help of a knock-out block.
The new nib is a beautiful EF gold nib from the 1950s.
Have fun with the video.
The video is for entertainment purposes only and is not a tutorial on how to repair Montblanc fountain pens. I assume no liability should damage occur due to imitation.

I wish I had that tool so I can deep clean my Montblanc 144.

Nib is written down. Sems almost impossible. But okay.
