I finally purchased my grail pen - an MB 146G with an OB nib and long ink window. I bought it for a fraction of the cost they sell in the market today. But, that's because its going to take some serious work to restore.
Cosmetically, to me, the pen is as good as it can be. However, it doesn't function, it requires a cork change. But, here are the issues:
1. The section is super duper tight. I have been soaking for 2 days, and applied dry heat once, but still no sign of budging.
2. The telescopic piston does not unscrew either - I've tried, trust me!
So, this means I am in for a bit of a challenge. Instead of simply sharing after everything is done, I thought I would start a sort of daily log to share what I am doing on a step by step basis so that I may attract good advice from experienced FPNers out there, or even just have curious members live through the suspense of this journey with me
I consider my skill level as intermediate (on a scale for recreational restorers). I have worked on about 40 vintage pens till date. I have some skill with tuning nibs, regrinding them to different types, restoring BHR barrels that are heavily oxidized, re-corking pistons, and re-sacing all kinds of lever pens. I am more interested in learning how to restore pens, than collecting them. And this is why I am attempting to restore my grail pen myself, instead of sending it off to a professional.
Here are some pics of the pen after a quick outer cleaning. I will update the next steps soon.
Notice that the nib is not a screw-in (below):
And the long-ish ink window (about 1/4th of the window still shows when capped):
