Additional inspection of the shipping box has turned up something interesting, and maybe answered a few questions. One of the bottom panels had been completely removed and later reinstalled. However it was flipped end for end. I was looking for signs of hot glue having held down a cardboard box and something just didn't make sense. There was a faint mark on the panel, but I didn't think it could have been right because it was under one of the plywood cross supports. Then I noticed the staple holes didn't line up with the staples. Flip the panel to line up with the staples and the faint mark from the glue falls into place perfectly with the area in the box that should have contained the cardboard box.
So, I don't think for a second the box was left out. The shipping box was opened in transit, items removed, and then the removed panel(s) were put back in place and the strapping tape was used to hold everything together.
I'd like to think the shipping box was dropped, broken open from the drop, and the cardboard box became separated. However I can find no damage which would support that idea. I checked the box for pry marks and damage while the delivery person stood and watched me. I assumed the strapping tape was original, not added in transit.
On a happy note, the stock wood is drop dead gorgeous. Can't wait to see it with some color added.
