I got my hands on 2 Lamy fountain pens.
The both were in pretty bad shape. So I decided to give it a try to restore them.
The olive Lamy is at least 23 years old and has been little used from time to time, but rests in the desk for about 11 years. It's in good shape so far.
The white one is stored in the desk, while the olive Lamy will be in real usage again. After a bit oiling and polishing it's in good condition and ready to scratch the paper!
It feels good to get this cult fountain pens back to life.
