Analogue/Mechanical Bathroom Scales (Saint Thomas Ward EX2)

Bathroom scales which currently don't work - if you stand on them the weight dial doesn't move. I think maybe some sort of spring has gone. The little dial underneath to calibrate them can still be turned, but it doesn't move the read-out dial any more. Thought they might be useful for someone who likes tinkering, or for some sort of project. They have a cork surface.
