Identification of old aircraft propeller

[zemic]

Hello,
Please could anyone know what the aircraft is the propeller? And what could be the price?
At the bottom is: 1801 and Z
I think it might be an aero-engine Argus As 10 (Arado 96, Messerschmitt Bf 108, Focke-Wulf Fw 56)

Thank you Peter

I have no idea, but Monte Chase at www.notplanejane.com may have some thoughts. He's the expert on variable pitch propellers . . .
