Awesome build up of this ship mate!.
I was glued to Blake's 7 as a kid & loved the Liberator. I must confess I did oogle over the Scorpio model more, probably as it was kind of Falcon looking & actually had MPC Falcon kit parts as detailing, but the Liberator was a cool design, still is!.
The studio model was quite large I recall & Martin Bower was the modeler from memory.
