...I did have to replace the barrel...
Interesting that you mention that, because I have a theorie about Pelikan 100 with metal sleeves. Of course I do not have large experience with this pens, that’s why I am interested to hear what you are thinking about it. So, my theorie goes like this:
Early Pelikan 100 barrels are made of cellulose acetate. This material is chemically unstable and tends to release solvents and acid vapors. Usually not a problem when the material of the binde is the same or vapor permeable at least, and when the pen is storaged at a well ventilated place of course. But I think it can become a problem when the binde is made of a vapor-tight material like metal.
I have this pen which seemed nearly unused when it came to me.
No HR discoloration, no brassing and crisp imprints. But the barrel was completely destroyed. It just broke in thousend parts when I tried to screw out the piston. Amazingly enough, the Pd nib too…
I replaced the barrel but I am unsure about storage of this pen and what is to do that the same does not happen again in a couple of years, decades...?
Now, what do you think about this?
