My own speculation of the Soviet era spy satellite from the Cold War. The main body is a converted Vostok capsule, the antennae and solar panels and main propulsion package are guess work, but the Soviets did use the Vostok capsules as spy sats.
Another view. I had wanted one of these toys since I was a kid, so when I finally got one on Ebay (don't ask how much I paid for it or the replacement parts), I wanted to do it proper.
I refurbished an old Remco toy from the 60's to look like one of the Mechanical Men episode from Lost in Space. I included the lighting from a X-mas tree kit.
