Vintage brutalist metal sculpture "Coming Together" figures in circle on marble

For your consideration is this interesting sculpture of abstract metal figures with arms stretched up joining together in a circle. I've seen similar sculptures, often out of the Netherlands, called "Coming Together" or "Reaching for the Top" but this one is somewhat different than the others I've seen. It is mounted on a black marble base.

I don't know anything about it other than it's cool. It was found on one of my treasure hunts north of Boston. It would fit right into your mid-century decor. 

It is 11.75” tall x 2.5” at widest. 2” square at the base. Unsigned as far as I can tell. 

It will weigh about 3 lbs packed safely. Thank you!
