I believe the Orion ship is based on the classic “Galactic Cruiser Leif Ericson” model kit.
Frank Henriquez’s fan page has this on the Star Trek connection:
Mike Okuda, who’s great work has been seen on several Star Trek series, has filled in some background info on the Leif Ericson design:
The Leif Ericson was designed by Matt Jefferies, designer of the original Star Trek Enterprise and many of the ships that appeared in that series. While the Leif Ericson never appeared in the original series, Mike mentioned that it did show up in a couple of places on Filmation’s storyboards for the animated Star Trek series in the early 1970s, although the ship did not appear in any of the finished episodes of the animated series.
