The stamp on the back (bottom-hard to see) says that it's "Series A, Number 1158 out of 2500"
Dont know much more then that. The rocker is in absolutely amazing condition..doen't really look like it has ever been used to be honest. It was passed down from an old woman who had it passed down from her mother.
It is a very beautiful piece...looks to be made out of a dark cherry wood of some sort.
