Yep, that's a Ben Lee Super Hen. Either that or someone made a really good effort to mimic his call. Looks like someone has sanded it and put some varnish on it at some point, as I don't believe they originally came with that kind of finish. I also think most were stamped and/or signed on the back and there is no indication of either on that call. As for dating the call, I would put it's manufacture date probably in the 1970's,...at least that's when I got mine as I recall.
