1980's granite abstract sculpture

What a beast! 
This is an 80s sculpture by an unknown artist but presumably Belgian. The artwork is a carved granite block. 
It has very nice lines and is a real piece of craftsmanship. Despite not knowing the artist this is a very quality piece of art. We keep looking for the artist but so far we have not found him. 
 
The sculpure is in very good condition, please keep in mind that it weighs +/- 40kg!
