Hi Blue Cat looks like a flywheel hears a picture kind regards Bob

Thank, Bob. Very odd !, like small buckets. I see that there is a hole in the side, I'm wondering if this is a water driven generator ? They were advertised in early 20s copies of hobby magazines like Model Engineer.

Hi Blue Cat you could be right there hear is a picture of some books i got of the person that gave me the generator one book dates to 1913 kind regards Bob

This is the sort of thing I was thinking of, the Whitney water turbine was advertised for years in Model Engineer about 100 years ago:

They are extremely low efficiency in domestic situations so I doubt your example is good for more than 6 volts. However, its a rare and unusual thing, I've not seen one before.

I can't believe that these are being made in this ECO-sensitive world. These things waste 25 litres of purified water every minute !!!        

Hi you are right there about that ebay item what use it it for apart from Education will spin my generator up and see what voltage i get kind regards Bob
