Two versions have been made of the Grip models; The Grip with round handle fire botton, and the Power Grip (50-2020) with a square button on top, similar to The Boss.
The base of the stick have arrows pointing to all moveable sides; on the Grip it is big, triangle arrows, and on Power Grip it is more like a clock.
Bot have a fire botton on base as well, and a selector to choose between Base or Stick fire button.
The Grip was also used in a bundle-joystick together with Red Ball and Bat Handle in the so called Wico Super Three-Way (50-2002), and Wico Three-Way Deluxe (50-2010)
Not certain about the age, but properly mid/late 80s.
