Also interesting. . . I saw on Wikipedia an explanation that
Penman was actually withdrawn from the market after new EU
regulations forced Parker to reveal that it contained uranium
compounds and is slightly radioactive.

I'm not sure if that presented a legal problem for Parker, or
merely a public relations problem.

This is the first I've heard of it, and I don't see any source for
this claim given in the article.

Here's the link to the Material Safety Data Sheet on Quink and
Penman inks:
