MLP SILVER SHIP - IS IT CAPTAIN SCARLET'S REBEL JET?

There appears to be a similarity bewteen the silver ship atop the Spacex MLP rocket and the rebel jet on the cover of the very final issue TV21, #242 (6th September 1969). There's a tinplate Japanese space rocket just like the rebel one too. I shall go and find it.
