On the "Periodicals" page you'll find a link to Vintage Guitar magazine
There is a classical guitar newsgroup that is probably the best place to post this query. In fact, newgroups are a great place to post queries like this, and a good place to hunt for the right newsgroup is the Usenet info center
In this case, a relevant newsgroup is "rec.music.classical.guitar".
Another group you should post to is "rec.music.makers.guitar.acoustic",
the acoustic guitar players' newsgroup. A great place for an acoustic
guitarist to hang on the 'net in general....
Good luck!
