Sure, I might have left well enough alone if the headlight had been visible but its all but impossible to see it inside the assembled car. Had I not wanted the body off for thorough cleaning, I never would have even known what was hiding inside.
Because of its slot and tab construction, lighting needed accessibility without disassembling the body. I was already pushing my luck disassembling the car a known second time Any more bending and those tabs are sure to break. Maybe I would never have had to change a bulb during my term as conservator but it would have been inevitable in the future. I'm saving a big disappointment for some distant owner.
I retained the roller truck, did away with the potential short producing solder joint and cloth tape connection and in turn fixed the electrical connection to the coil coupler. When I come across a proper clip in light socket, it again will be illuminated.
Pappy: The 1666, associated whistle tender and cars were only part of a larger package of PW Lionel. Everything pertaining to the '46 set were loose items without boxes and below average, high milers left in some damp storage. It all cleaned up well and other than missing it's front truck the 1666 runs and whistles great. The later PW, while in better overall condition still suffered from moisture. I have spent most of the last week furiously cleaning and reviving the lot. You'll probably see more of it posted elsewhere when I take a breather and snap some shots.
