ISS Integrated Truss Assembly (ITA) mockup

[hinnersd]

Before Space Station Freedom became ISS, McDonnell Douglas had firmed up the designs for the SSF truss elements that eventually became the ISS truss elements and built full-scale mock-ups in Huntington Beach; the first half of the original SSF assembly sequence, that is, S3/S4, S2, S1 and M1(renamed S0 for ISS).   There's a poorly reproduced picture of the assembled mock-up truss from a 1993 SSF redesign report so I know they were built and lived at Huntington Beach.   Any former McDonnell/Boeing employees know what happened to them?   Anyone ever seen them?  It would be the only produced S2/P2 truss element.   

These would be elements that were produced in addition to the S0, S1, and S3 STA's.
