Here again is another beautiful guitar for your consideration, it's a 1974 Martin D-35 S. The S stands for slot head, 12 frets to the body. This beauty plays and sounds just amazing. This is the same model that Paul Simon and George Harrison played. This is not a guitar that is part of the Martin product line, and is very hard to locate one that is in this condition.
Any other questions, feel free to either email or call me at (646) 236-7136. Thank you!
