Have you looked at Annapolis Performance Sailing? I did a quick check, and they have an extensive selection of one-design parts, including the Optimist items you're looking for. Check them out on the web.
You may also want to have a look at David Mas's website . He is a good sailmaker and spar distributor. He was in the Athens Olympics with the Spanish team. I don't know if he was also in Beijing (I haven't seen him in a while). His wife was years ago the Spanish champion in Optimist and she is coaching an Optimist team, including their son Santi, who was Optimist Spain's Champion two years ago and did a good European Championship (I don't remember his final position). Similar age to Fred, I would say, and a hellova sailor too.
With the Euro-Dollar current rates it may still be better to buy in the US, but have a look at the prices (they are displayed in the website).
(I know you don't like Spain. Me neither. But since they are based in the Barcelona outskirts, you can consider you are crossing two borders if you approach them).
BTW, David is definately more a craftman with his little shop and a few employees doing a good job than a businessman: his website socks, and they don't speak English (he definately doesn't, and I don't know if someone in his shop does), but, you know, we are all old romans speaking not that different dialects...
