Found the propeller of a Curtiss in central Italy

[gradoli.v]

Good evening,
in the countryside of Capalbio (southern Tuscany), was found during the war, a propeller. Today was saved only a blade.
In the bottom of the blade is engraved with the brand Curtiss.
There are also many acronyms. From top to bottom:
43
DWG. NO. 89303 - 24w CHG - M.
SER. NO. 74159
FORG. NO. 79605
Can you tell me which plane corresponds to the blade?

Thank you
Victor

Curtis electric propellers were used on a variety of aircraft, P-40, P-47, B-26, C-46, etc.. Your's is most likely from a P-40.
You will find the drawing number (DWG 89303-24w) here, http://www.wwiiaircraftperformance.org/P-40/P-40.html

In fact, in that area, were shot down some P - 40.
Thanks for the answer!
