Bob, just from the head stamp code. Listed on the IAA headstamp page linked below. And yes I do see that WB III says that FN ammo was actually produced in Bruges.

No idea about the writing on the box, also dated 2 years later than the head stamp? Google translator says "con bala de madera" is Spanish.
