Star Trek Mobile Paperboard Vintage ca. 1979 missing some pieces

Pre-owned vintage mobile that seems to have most pieces but not all. X header has 5 strings - one on center and 4 at edges. 4 ships hanging and 1 separate ship needs to be attached. Then some pieces I can’t figure out! Some tape here and there but mostly the pieces are intact. I think with some glueing (nothing glued so far) to make the tabs stay in, and perhaps some strategic harder cardboard inside some spots to make it more resilient would set it up pretty nicely!
