Keep in mind the bright shiny copper color one is just a modern interpretation of what it may have looked like when it was complete, and what was found was just the small fragment next to it.
The article just neglects to mention this directly.
The model seems to make a lot of assumptions based on such a small fragment.
It's a "highly detailed reconstruction" (bottom of TFA). Agreed that TFA is light on details and annoyingly disables text selection, which is something I haven't been annoyed by since 2007.
Not only does it manually disable text selection, it also disables the right click menu and most ways of opening the dev tools... for some reason... (you can still reach dev tools using the top right menu on chrome though)
Using "Find" in my browser says those words are on the page somewhere but I cannot find them anywhere.
Weird. It's the last sentence in TFA.
I think it actually slipped under the ad. Using a browser with Adblock I see it.
It would have been bright and shiny when new back then too
