Possible henry Moore Sculpture

Shown is a sculpture made out of some type of heavy grey metal.  It is a sculpture of a woman rocking a young child.  It is 12 lbs 9.6oz, 15" long, 13" tall. 

There appears to be a signature on the bottom of the chair near the back of the chair.  I seem to be able to see an o and r but may be wishful thinking.

I read on the internet Henry Moore did some late work in iron and wondering if this could possibly be one of his late Rocking Chair sculptures.

Good
