Hi everyone. A few years ago I bought a Spanish guitar for $100, and I've been playing it ever since. Now I have a mind to sell the guitar, and, since it seems like it might be valuable, I'm trying to identify when it was made, where it was made, and who made it. The man I bought it from said he originally bought it in England in the 60s or 70s. The only markings on the guitar say "Juan Santos Concert Spanish Guitars / Model A 6," and Google has been absolutely helpless in providing me with any leads, except that it brought me to this website. So I ask you, luthiers, is this Spanish guitar of mine at all valuable? It's in excellent condition, by the way.
Here are a couple of pics:
Thanks in advance for any help you're willing to provide.
