I wish I knew more about these early New York Martin guitars. This one is circa 1875... I think. It is hard to know everything and no one would ever accuse me of that. There are some repaired top cracks but the Rosewood back and sides are very intact. The action is close to acceptable but a neck reset could be a good option. The tuners are modern and work well. This is a great little guitar that is very loud and has great sound.
