HG Toys No. 892 BUCK ROGERS in The 25th Century Galactic Play Set - Pt 3 The Space Station (Flying Saucer)

HG Toys called this flying saucer a 'Space Station' in all of its space playsets that I'm aware of. It's quite a large affair in relation to the figures included in these sets and I'm wondering if they ever offered it as a separate sale item along with larger figures OR was this made with tooling from another company that HG Toys acquired (as is the case with other HG Toys playsets that I own)??? The station consists of a disc / hull, three legs, dome, and retracting stairway / ladder and measures 10.5" (26.67cm) diameter x 6.5" (16.51cm) H overall. While I've never seen anything other than a yellow disc with red dome, the box art clearly shows a blue disc with red dome. Molded into the top of the hull in two parts are: "STAR STATION", "X-5" as shown in the photos

***CORRECTION TO YESTERDAY'S POST:

THE SPACE COMMANDOS ARE 35MM NOT 25MM***

Box art shows blue disc with red dome.

The Space Station is quite large and that ladder looks out of place with those diminutive figures
