Here is a new lamp plate with the bell timing bi matilic strip on it. Note that on the lamp holder the center contact is ground and the shell is hot. In the second photo you can see where a rivet is used to connect the underside buss bars to the lamp socket shell. In looking at the part it is not clear how the non contact end of the heater wire gets connected to the ground buss bars. I would guess it is clamped in that riveted joint. The large hole in the ground buss bar is where a mounting screw attaches the lamp plate to the support frame, which is screwed to the tender frame. Other wires solder in the eyelets as required for the various tender models.
Also attached is a photo of the warning that I referred to in the previous post. It is not as I recalled it. This comes from Dennis Walden at Just Trains. He still has these parts for sale.
