T'Bone's also got a good trailer resource page:

Problem is the original poster is looking for a different trailer:

The 2nd one uses the triangular shaped Star Wars font from tghe Tommy Jung poster. This is the trailer I am looking for. The Fox trailer (not original) without Williams soundtrack.

I haven't seen this one, fairly certain it hasn't made any home video release. If they return hopefully they can specify what audio was part of the cut. Their description sounds like the 1978 trailer just with different music.
