Vintage metal wind up robots & rocket

These are around 15-20 years old. All robots wind up and walk, the silver robot no longer has sparks in his eyes. The rocket is 39cm tall. When in the ‘down’ position and the tip of the rocket is touched, it bounces up as if to launch, but it springs a bit too much as I think a cog has come loose. Still looks cool just standing there though :) Pick up in Howick or happy to post. Thanks!
