Does anyone have any information on what four bladed propellers were used on the Douglas XB-19A powered by the Allison V-3420-11 V24 engines.
I have two very large propeller blades that I have been trying to identify, they appear to be Curtiss Electric hollow steel blades. The part numbers that are on the butt of the blade are not very visible.
Here is a link to the pictures of the blades and dimensions:http://www.aeronca.com/mysteryparts/
