I get most of my stuff off eBay, and have encountered very few examples of damage caused by the shipper, be it UPS, Fed Ex or the USPS.
Most damage I have had has come from the seller wrapping the item so tightly in bubble wrap that small parts get broken off. The most recent example is the C&O 2-6-6-2 (Lionel #6-28075) I got myself for Christmas (π). The pilot, one of the steps from the front platform to the boiler walkway and the small, scale size front coupler were all broken off, due to the tightness of the bubble wrap (and being die cast, as opposed to say, brass). Fortunately,the pieces were present, so I think I can repair the damage. π
So consider this a gentle reminder: the inner wrap is just as important as the box you ship it in. π

PS: this is a very impressive model...and yeah, I already opened it; I'm old and can do stuff like that!π
