“Liberator” Space Ship
The original featured in the first three series of Blake’s 7, the sci-fi series created by Terry Nation (it ran from 1978–81).
I couldn’t find any decent photos of the ship (nothing that I could easily scale off) but I managed to buy the Corgi model on eBay.
The model is entirely Meccano (it should be all white) with the exception of the ball, which I think is supposed to be its method of propulsion since it pulsed when in flight. In my model a light flashes — the light was recovered from an old bicycle front light. The ball is the dosing ball from washing machine liquid.
