As I was about to post this, I saw Procyon's post on his beautiful silver and gold sleeve fillers, purchased on Ebay....well done!
My pen was found at a country flea market a few days ago. I'm trying to decide whether to restore the pen myself (I have some experience) and keep it, or sell to someone else and let them have it restored. I certainly don't want to risk damaging it. If I decide to proceed myself, I would appreciate any advice on how I should proceed.
