The pictured empty Masonite meter panel housed 5 AC Volt and Amp Meter pairs monitoring 3 pw ZW "A" throttles and 2 "D" throttles supplying 5 power districts. Layout dismantled March '08.
The panel is designed to mount about any inexpensive Analog Toy Train Meter, having a 2" barrel and 4 attaching screw post/nuts.
FREE, first come first served Forum post. If 5 positions not needed, it can easily be cut down to 2, 3 or 4 pair positions.
