I finished #3 gun. It has a little extra with it so I figured I'd throw up pictures for those interested....
The box is just decorative so to speak. The gauge is a meat thermometer, it has two lights and one push button switch, and on the side is a fuse compartment (above the cord on the left side). The switch and lights do not work. The box had leather in the back to allow it to be worn on a belt. Just something I was toying with to give a little extra to the gun.
A close up of the box.
