Antique Dove Tailed Baby Crib / Baby Rocker

I'm guessing it's from the mid 1800's. The size is.... At the bottom is 12" x 36". At the top is 15" x 41". The rocker "legs" are 6.5" high x 28" wide. The "Shade holder's tongs" are 13" long. The 3 brass knobs are 5 inches apart. The boards look like 1 piece each. I do not see seams so the sides are made from solid 12"x41" boards. The head board is 14"x17" but it was broken at the top and repaired. There are 2 or 3 scratches on the inside. There are 4 screws holding the "legs" on and the screw heads are flat but I do not know what the ends of the screws look like since they do not look like they have been removed in the last 50+ years and I don't want to damage it.
