I once saw one of those rare Martins, Rap. It played "Yankee Doodle" when you turned the crank. It also had a bullet hole right through the front and out the back in the lower bout. Some ex-Confederate must have taken offense, I suppose. Anyway, I would have bought it, but just didn't have enough money at the time, and by the time I had gotten together the money and rushed back...it was gone! (sob!)
