I had this. It was fab. the way that you could produce about three different spaceships from it was especially good. I used to play with it in the garden a lot with my Airfix World War 2 soldiers :-)
So cool! Really brings back the memories.
That commercial seems so familiar to this American :-) that I wonder if the same commercial was used in the US, but with "American" voices instead.
I think that's likely.
I had the Starbase, which was mostly cardboard and several plastic pieces for cranes, guns, etc. It did make for a great landing pad and base. It even came with a few astronaut crew members. Ah, good times.
