I was recently contacted by Esteban Egaña Silva who has a very interesting guitar collection which he wishes to sell.  As he mentions on his blog the popularization of the guitar in Chile is due to Spanish immigrants over the years.  You can find an entry about how the guitar “arrived” in Chile and another detailing some of the guitars he has for sale here.  

He tells me that there are more guitars than those that appear in the blog. My contact with him was through facebook but I imagine that you can send him a message from his blog.
