This is the website of a French luthier. However, the really fun part of his website is that he's got a section at http://www.luthiers-mirecourt.com/documentation.htm that has a bunch of historic catalogs and instrument books. Some of these look like he scanned the original and mad new plain text documents. http://www.luthiers-mirecourt.com/annuaire_1925.htm is a cool one to start with. At the very, very least, it's an excellent timewaster.
