Hi dcd,
First of all welcome to our little fountain pen nuthouse!
Now, for a vintage Pelikan, the most obvious person to try is Rick Propas, alias the Penguin. Here is his site:
The Penguin Site. Just check his Pelikans for sale.
Alternatively, there is Daniele Teppa, in Italy, who posts Pelikans for sale here in the Marketplace on a regular basis, but whom you can contact here as well:
Pen and Pencil. Also check out her Pelikans. If you want to buy from her and want to know what is available, just email her.
And then there is also Regina Martini. Here is her site:
Regina Martini's site.
Anyway, HTH, warm regards, Wim
