Guest:Pete Peterson,
Thanks for your words. I wouldn't sweat the issue of the finish being somewhat stripped off the back of the neck of your D-21, too much. Many older Martins have the finish on the back of the neck worn off from playing. The key is NOT to refinish it. As long as it plays comfortably and you can still slide up and down the neck with ease, it shouldn't be a significant issue. Lately the D-21's made in the 60's in good shape that I've seen at various dealer web sites, appear to be selling in the $3,250.00 - $4,000.00 range.
