Default Propeller Identification

I'm trying to identify a propeller described as being from the 1910s and made of aluminium alloy.
It's not something I had seen before but is identified as being aviation?

Inscription:
DRG NO.120
SNO.12

Measurements: L 310 W 50 D 40mm (L 12 3/16 W 1 15/16 D 1 9/16")

Any help with identification would be much appreciated.

I doubt that it's aviation related, although that's always possible, but it's not typical of any propulsion system that I've seen. That doesn't preclude it from being used on some kind of wind generator or similar device. It has a left hand thread, which is the opposite of the more commonly seen right hand thread direction.

I agree with Dave. It dates from c1917 to late 1930's and is an auxiliary prop which drove an electric generator to provide the power to pump fuel from a main tank to an auxiliary tank, or to provide electricity for instruments and lights.

With kind regards,

Bob
