Here is another picture that didn't come thru in my earlier post. It is the one of the original 30/30 Loop Gauge and the Aftermarket style showing the back sides. Loop visible at bottom of Induction Style, with the Aftermarket style gauge showing screw wire terminals doubling as mounting bracket fasteners as well. The info on the part numbers is in the first 9N MPC too.
