'Morning Bob,

I can't identify any of this data. But I can tell you that it is a late WW1 auxiliary prop. It would have been mounted in the airflow, probably from a wing strut and probably intended to power a generator of about 500 watts, but also possibly for a fuel pump, usually made by a firm called Rotherham, although these props were normally twelve inches in diameter.

With kind regards,

Bob

thanks again,at least it is ww1.
