The finale to this episode of my tales of USPS woe, is that in the end everything is going to be okay, thanks at least in good measure to the care taken by the seller to provide truly excellent packing to protect it on its nearly three-week journey through HELL and beyond!
The item itself had some displaced parts, showing that it has been knocked around pretty good in transit, though nothing was actually broken amazingly. The water damage to the packaging, which USPS just wrapped over multiple times with stretch cellophane, likely as much to keep my package from dripping on others rather than to protect mine which had already been wetted, so also probably needed help to hold mine together.
Upon opening, the inner manufacturers' box felt a bit clammy, but not actually soggy, and has, since opening, dried nicely. The plastic item itself seemed wholly unaffected by the moisture, even though there are a few iron parts like fasteners and such that could have rusted but did not.
I'd say that both me and the seller got real lucky on this one, mostly due to the great job the seller did in packaging well enough to defeat repeated attempts by the shipping gorillas to lose, drowned and destroy this item!
Somebody say AMEN!!! ;C)
