Antique Rocker may be from Germany

I'd like to know if anyone knows anything about this rocker. Thirty-three years ago it was given to me by a seventy year old woman friend. She told me that it was her grandfather's, who was a stonecutter in Germany. I don't know if he brought it from Germany with him, or if he acquired it here in America. I've never been able to find anything that looks similar. The seat is not original, I believe it was originally caned.
