This was one of those Postman Pat type animated cartoons, where it's actually models walking around the screen.
It was about a machine, called Bertha, that could make absolutely loads of different things.
The theme tune went something like....... ahem...... "Bertha, lovely Bertha, some times I think you're a deeeeeaaaam....."
Personally, in a fight between Bertha and Chokablok, I don't think Bertha would have stood much of a chance. Call me picky if you like, but a machine that can supposedly make anything is bound to break down far more often than one that has Derek Griffiths calming hand guiding it.
After Bertha, they went on to make Charlie Chalk. Good plan.
