Actually, you can probably add an unnamed OV-106 to the list.  NASA got
approval a while ago to replace the structural spares used to build
Endeavour.  (This also keeps the option of another orbiter open a bit
longer, in much the same way that the original structural spares kept
production facilities going long enough for a Challenger replacement
to be possible when it turned out to be needed.)
