Lee,

There's the obvious UK publications such as 911 & Porsche World, plus Classic Car & Sportscar (which has a European section). There's plenty of good websites for this market too such as:
www.ddk-online.com
www.porscheclubgbforum.com
www.classic-chrome.co.uk
www.early911.co.uk

In France you have publications such as Nostalgia (www.editions-pegase.com)

Not a comprehensive list, but hopefully that will give you a start!

Happy hunting.

Will
