Well, there is
Chic's most awesome website with plenty of amazing stuff.
But whenever I dig through the TriStar section I'm so totally puzzled by the stated dates as they absolutely don't seem to go together.
Several pictures of HHK on the assembly line (like your attachment in #99) clearly show it with ln 1118 behind the cockpit and reg on the #2 intake. Chic also has some amazing pics of it on roll out. Check.
But then the set of air-to-air shots over the US are said to show first flight (July'75), but the airframe already wears the "Super TriStar" titles and reg on tail.(??) - I've seen images showing the aircraft with blanked out intake reg but wearing its test reg N64854 (ln eliminated already) on what I suppose to be first flight.
The set of Chic's images by Laurie King at OKL - August'75 - also show "Super TriStar" titles etc.
But then there's that September 02 and pics show HHK being welcomed at Kai Tak with the reg on #2 intake again (??!!??) An absolute mystery to me, but "Chic" was at the party. I'm so absolutely curious. Sadly we can't ask him anymore. R.I.P.
But I think we agree that this is what NG's model should look like:
