ALTARES

From the standalone TV episode ’Into Infinity’ produced by GERRY ANDERSON.

1/144 was the scale of the AIRFIX ‘real space’ model kits such as the Saturn V and Vostok rockets. Their ‘Space:1999 Eagle Transporter’ was in something like 1/72nd.

I could imagine AIRFIX in the 1970s trying something clever with the solar panels. Possibly something like the ‘rainbow effect’ stickers that came with the AMT / Matchbox USS Enterprise from ‘Star Trek The Motion Picture’.

Most likely white plastic and coming in at about 16” (40cm in length).
