Can anybody out there tell me what this is?
I know it is an old medical device and is 50x30x10 cms in size and has a very precise clockwork motor. When wound up, the circular piece at the top rises up about 30 cms and slowly goes back down as the wind finishes.
It comes in a a very well made aluminium box.
Nae prizes for anyone who knows, just the satisfaction of knowing you are a genius.
