Originally intended as a student instrument, but now the 0-17 rates as a first class player's guitar. Martin in those days built every instrument with the same quality, just different woods, sizes and cosmetics; mahogany is nowadays is favored by many, and the small size is appreciated now that we've recovered from the "bigger means better" mistake. The top and sides have been refinished normal. There's a new slightly larger bridge plate and what might be a small hairline in the treble side; you can't get air through it, which means it's been glued properly or it's just a finish crazing.
Our "Cash price" policy: unfortunately, the credit card companies support "swiped" charges in which the card is physically run through the card reader. Phone-in charges are charged at a much higher rate (to the seller) which can take quite a big chunk out of a high-dollar sale. Thus, for those call-in sales, let's discuss the issue at the time; hopefully, we can figure some way to deal with it.
