There is a guy who hangs out on the newsgroup:

rec.music.makers.guitar.acoustic

named Joe Mack. He is the (I think) Northwest representative for Martin Guitars. He seems to field a lot of the Martin questions from folks on that NG.

There are many kowlegable people there who can answer questions about Martins if he doesn't.

You can always wait until he posts and then get his email address and send him a personal email (but don't tell him who told you to do that ;}).
