Maybe you can ask Laurent Pflughaupt (le-callysteme.com) or Laurent Rebena (calligraphie.com).

Thanks for the info.
(And by the way, if anyone knows about online shops that would do that, I would be fairly interested, even though I doubt these exist)

If you are looking for steel pen nibs, you might want to try John Neal Bookseller (www.johnnealbooks.com).
Besides books, they sell a wide variety of pens, brushes, nibs and other lettering and calligraphy tools. They are located in North Carolina and ship to Europe.

I've bought mine here. Some were quite rare I remember him saying. So it's a shame I lost them. Not all info in English, but I assume he answers questions in English.
