Hi there, I have a website www.classicwindsurfing.com that is dedicated to preserving (and using) old school (pre 1992) windsurfing gear. Part of the site is a collection of Mistral, Neil Pryde, Gaastra catalogs (1980-1992). At the moment i don’t have a complete set and some of the ones there are partial or poorly scanned. If anybody has catalogs I would love to get a PDF copy or even buy them from you. Thanks Jon
